The couple made their relationship public in October when they were seen for the first time together at the Rugby World Cup final at Twickenham in London.

They were next seen walking arm-in-arm down the red carpet ahead of the Golden Globes awards ceremony on Sunday, although Miss Hall did not appear to be wearing an engagement ring.

It will be Mr Murdoch’s fourth marriage, having divorced Wendi Deng in 2013. His first marriage was to Australian Patricia Booker and he then married Glasgow-born journalist Anna Torv.

It will be Miss Hall’s first official marriage after an unofficial ceremony with Jagger in 1990 was declared invalid after the pair ended their 23-year relationship in 1999.

Australian-born Mr Murdoch has been careful to ensure the financial future of his six children, with each being given a share in News Corporation's profits.

Only James and Lachlan, Mr Murdoch's two sons to second wife Ms Torv, are directly involved in the running of his media empire, which owns the Sun, the Wall Street Journal and Fox Entertainment Group.

It is understood Ms Torv, who was married to Mr Murdoch for 32 years, walked away with a settlement worth $1.7billion when the couple divorced in 1999.

Meanwhile Ms Deng was given a $44million New York apartment, a $20million property in Beijing, in addition to assets as per the couple's pre-nuptial agreement, when she split from Mr Murdoch in 2013. However, she has no equity in News Corporation and no voting rights in the business.

It is not yet clear whether Mr Murdoch plans to give Miss Hall, who has an estimated fortune of $15million, a stake in the company.

Mr Murdoch and Miss Hall, originally from Texas, were introduced two years after the end of his 14-year marriage to Ms Deng.

His split from the Chinese businesswoman - who he met when she was interning at one of his TV stations - amid rumors of her 'infatuation' with former British Prime Minister Tony Blair.

After informing their children of their blossoming relationship, Mr Murdoch and Miss Hall went public in October at the Rugby World Cup Final in London, where they sported matching Australia scarves in support of the mogul's home nation.

The couple's joy was apparent as they walked into the stadium arm-in-arm, smiling and waving flags.

They were later seen sharing a joke as they watched the action from a box, before Mr Murdoch leaned over to give Miss Hall a tender kiss on the cheek.

At the time, a family friend of the Murdochs told The Mail on Sunday: 'It's all very new. They are really enjoying each other's company very much.'

Another friend elaborated: 'He is very fond of her. There is no question that they are a couple,' before adding that both Rupert and Jerry's children were aware of the relationship.

FAMILY BUSINESS: THE TANGLED WEB OF RUPERT MURDOCH'S BILLIONS Second wife: Rupert Murdoch with Glasgow-born journalist Anna Torv in 1997. The couple divorced in 1999 after 32 years together With six children from three marriages, Rupert Murdoch's family is a complex machine that is a constant source of interest for international media. And its fortunes are inextricably tied with those of News Corporation, Mr Murdoch's empire in which his four daughters and two sons each have a share. The tycoon, 84, who has an estimated personal fortune of more than $12billion, is understood to have included his six children in a large stock pool which was valued at $2billion in 2006. The understanding is that the children will each have an equal share of the takings - some $300million each. Prudence MacLeod, 57, is the billionaire's only child from his first marriage to Patricia Booker, a flight attendant from Melbourne. The couple were married for 11 years, divorcing in 1967. Ms Booker is believed to have walked away with a divorce settlement worth $1.2billion. Mrs MacLeod, known as Prue, married a News Corporation executive. She is believed to be included in the stock pool as well as having voting rights in the company. It is not clear if she has any other involvement in the family business. Mr Murdoch had three children with second wife Anna Torv, a Glasgow-born journalist who worked on the News Corporation-owned Daily Telegraph in Sydney. The couple divorced in 1999 after 32 years together. Elisabeth Murdoch, 47, boasts a significant personal fortune and her business acumen has long been lauded by her father. Her UK-based TV production company Shine was bought by Rupert Murdoch in 2011, and later merged with other divisions by parent company 21st Century Fox. Ms Murdoch, who is twice divorced, reportedly walked away with $320million from the Shine deal. However, any future role within News Corporation is unclear. She was critical of her brother James' handling of the phone-hacking scandal which led to the demise of News of the World. It is only Mr Murdoch's two sons with Ms Torv who are directly involved in the running of his business. Women in power: Mr Murdoch with ex-wife Wendi Deng, right, and daughter Elisabeth Murdoch in 2008 Lachlan Murdoch, 44, has been reinstated 10 years after breaking away from the family to set up his own empire in Australia. He has returned to take up a role as co-executive chairman of 21st Century Fox and his future within the family business appears assured once more. Meanwhile James, 43, who has an estimated net worth of $160million, was recently installed CEO of 21st Century Fox. He faced widespread public criticism in the wake of the phone hacking scandal at the News of the World. He was chairman of the publication's holding company News Group Newspapers when news of the scandal came to light. Mr Murdoch's youngest children, 14-year-old Grace and Chloe, 12, were born to third wife Wedi Deng, whom he divorced in 2013 after 14 years of marriage. Ms Deng was given a $44 million New York apartment and another in Beijing worth about $20 million and undisclosed assets as per the couple's pre-nuptial agreement but she has no equity in the company and no voting rights in the operation. Grace and Chloe were included in the $2 billion stock pool back but are not thought to have any voting rights. It remains unclear how, if at all, Miss Hall will be factored in to the operation of the business. However the former model, who boasts a personal net worth of some $15million, would stand to inherit part of the family fortune. Advertisement

The couple's next public appearance was at the Golden Globe awards on Sunday, where they walked the red carpet alongside Mr Murdoch's son, Lachlan, and daughter-in-law, Sarah.

Miss Hall looked elegant in a floor-length black gown, with sequin detail that made the most of her slim figure. Mr Murdoch opted for a dapper suit and tie combination, finishing the look with a pair of tinted glasses.

Inside the ceremony, the couple shared a table with some of Hollywood's most high-profile A-listers, with Miss Hall seated next to Best Actor in a Motion Picture nominee Matt Damon.

After more than 20 years on the arm of Rolling Stones frontman Jagger, Miss Hall is used to rubbing shoulders with the brightest stars in showbusiness.

The couple have four children together, Elizabeth, 31, James, 30, Georgia May, 24, and Gabriel, 18.

The model, who was one of the most photographed models of the 1970s, dated Roxy Music musician Bryan Ferry before meeting Jagger.

After their split she had a series of relationships with younger men, including film producer George Waud, London banker Tim Attias, and scientist Armand Leroi, her most recent boyfriend.

Before Mr Leroi, she enjoyed an intense romance with millionaire property tycoon Warwick Hemsley.

Miss Hall has previously spoken about how 'getting married again is a nice idea' but that she hadn't met the 'right person' since her divorce from Jagger.

In an interview three years ago, a friend of Miss Hall said that if she did marry again she would 'probably have to forfeit her magnificent home in Richmond, South-West London', which the couple shared after buying it in the early Nineties.

'Above all, Jerry craves security,' another friend said. 'She likes to feel that she is going to be taken care of by a man — which perhaps comes from being raised dirtpoor in Texas.'

While her relationship to Mr Murdoch may seem unlikely to some, their appearance at the Golden Globes would have been no surprise to those who know him best.

Mr Murdoch attended the ceremony with ex-wife Ms Deng on a number of occasions, where they joined scores of stars on the red carpet.
