Rumour has it: Long-term loves Kit Harington and Rose Leslie are engaged, sources have claimed

'They're yet to set a date, but told friends and family last week that they've got engaged,' a source told The Sun.

'Kit's known for ages he's wanted to marry Rose but he wanted them to get a house and settle down a bit first.'

The insider claimed Kit felt marriage was the natural next step for him and Rose, also 30, after they moved into a £1.75million mansion in East Anglia.

'After moving in together in January he felt it was the right time to take the next step,' they said. MailOnline have contacted reps for Kit and Rose for comment.

'I've moved in with my other best friend Rose, so I'm very happy,' Harington told chat show host James Corden in June.

'It's going well, so she's got all sorts of ideas for the house.'

'I said to her, cause she's moved into my house, "Look darling, it's important that this is our space. That it feels like our space.

'That you haven't just moved into mine. Move anything you want around, change anything, chuck anything out".'

The couple - who met on the set of the HBO fantasy series - purchased a medieval 15th century timber home in the English countryside.

The seven-bedroom house boasts a medieval-inspired moat around the property that sits on eight acres in East Anglia.

The proposal claims come after the couple denied they are engaged back in July.

The stars shut down reports that they are to wed, after Life & Style claimed the pair were 'planning their nuptials'.

The U.S. tabloid alleged that Kit had popped the question over a romantic dinner, leaving his long-time girlfriend in tears.

'Kit recently cooked Rose a romantic candlelight dinner and proposed to her. She burst into tears and immediately said yes!' a unnamed source claimed.

However, the stars' reps denied that the pair were set to tie the knot at the time.

The Scottish actress appeared on GOT as Ygritte from 2012 to 2014, while Kit has played Jon Snow on the series since its premiere in 2011.

Rose, who found fame as servant girl Gwen in Downton Abbey, is said to want a traditional wedding 'with kilts and bagpipes' in her native Scotland, Life & Style reported.

At the season seven premiere for Game Of Thrones in Los Angeles, Kit spoke about his relationship with his former co-star.

'I think that's the really special thing about it is that we met on this show and here we are seven years down the line back here promoting season seven,' he said on the red carpet.

'I mean it's mad. It's such a special thing. I'm so privileged,' he added.

Life imitating art: Kit revealed how 'easy' it was to fall in love with Rose while they were shooting Game Of Thrones

While the actor didn't divulge too many details about their relationship, which had apparently been on and off since 2012, he said the couple were 'very, very happy.'

He also revealed last year how 'easy' it was to fall in love with Aberdeen beauty Rose.

Recalling his favourite memory of shooting GoT, he told L'Uomo Vogue: 'The three weeks in Iceland where we shot the second season... because the country is beautiful, the light of the North magic, and why it was there that I fell in love.

'If you are attracted to a person and in fiction is your love interest, it becomes easy to fall in love.'
