The daughter of ISIS execution victim David Haines today accused Sir Rod Stewart of pursuing a 'cheap laugh' in an 'appalling' film where he appeared to stage a mock execution in the desert.

Bethany Haines, the daughter of David Haines, has branded the singer's actions 'disgraceful' and told MailOnline: 'This actually happened to my dad and it's not something to joke about'.

Today Sir Rod, who is worth an estimated £160million, made a humbling apology after he appeared to mimic an ISIS beheading in a 'sick' video made while frolicking in the desert with his wife Penny Lancaster.

He said that he had been 'larking around' before his show in Abu Dhabi last night and said it was a Game of Thrones reenactment not an ISIS execution.

Bethany's aid worker father David, 44, was captured by extremists beheaded in early September 2014 by executioner-in-chief Jihadi John.

As the shock video emerged she told MailOnline: 'I think it's disgraceful that a celebrity who is thought of as a role model would do this sort of thing. There's some things that are funny but that isn't.'

She added: 'I had a lot of respect for Rod Stewart, now you couldn't pay me to listen to his music'.

David Haines' widow and Bethany's stepmother, his second wife Dragana, told MailOnline: ‘It is immature and completely irresponsible.

‘The least he can do is apologise to all the families who have lost their loved ones in such a horrible way.'

Furious: Bethany Haines, pictured at the funeral of her father David Haines, right, has branded the singer's actions 'disgraceful' and told MailOnline: 'This actually happened to my dad and it's not something to joke about'.

Dragana, who is fighting breast cancer, added: ‘All we want to do is try to live our lives in as normal way as possible under the circumstances. I want my daughter to have happy childhood and she does not need to be reminded of her loss every now and then by people who unfortunately find it laughable.

‘And at this point in time, I don't want to be stressed by such things even more. I need all my strength to beat the cancer and be strong for my little big girl.

‘To them it might have been just a joke, but for us it is additional stress and more pain.’

Upset: Dragana Haines,44, pictured on her wedding day with her late husband, said Sir Rod 'should apologise to all the families' of those who have died

Rod's actions mimic the large number of murders carried out by ISIS' executioner-in-chief Jihadi John, who beheaded dozens including Mr Haines and Alan Henning, 47, from Salford, in 2014.

Jihadi John was later eviscerated in a drone strike after becoming the world's most wanted man because of his barbaric acts.

Bethany Haines said: 'Instead of putting his time and effort into a cheap laugh at people's expense, he (Rod) should be putting his time and effort into helping the people affected by what's happened in Syria and everyone who's been affected by Isis.'

Critics today called the stunt 'sick', 'stupid' and 'offensive' to victims and their families with some saying he should lose his knighthood.

After the video emerged Sir Rod said that he had been 'larking around' before his show in Abu Dhabi last night and said it was the execution was a Game of Thrones reenactment not an ISIS execution.

He added: 'Understandably this has been misinterpreted and I send my deepest apologies to those who have been offended'.

Rod's video was posted on Instagram by Penny Lancaster as the star performed in Abu Dhabi last night.

He is is on a world tour and will head to America next, with dates in Las Vegas and Florida before going to Mexico. He performed at the 02 in London last weekend.

The mock execution film was captured by his wife Penny as they did a 'Beatles-style' walk across the top of a sand dune.

But after doing an Abbey Road inspired video Rod then pretended to behead a friend while his wife Penny and others rolled in the sand.

Penny sat on the dune not knowing that her husband was carrying out the mock execution behind her.

Later the 72-year-old singer soaked up the sun with his wife, with the Loose Women presenter showing her her famously long legs in a pair of tiny denim shorts.

Clearly relishing the warm sun, Penny posted a picture of herself relaxing on the sand with her husband alongside the caption 'sandy afternoons.'

Penny wraps an arm around Rod who is wearing an unbuttoned white shirt, trousers and a pair of sunglasses.

Both the couple, who have been married for nearly ten years, were smiling broadly as they snuggled up together.

From re-enacting the Beatles' Abbey Road crossing to spontaneously playing out Game Of Thrones, we were simply larking about pre-show. Understandably, this has been misinterpreted and I send my deepest apologies to those who have been offended Sir Rod on his 'misinterpreted' film

In another snap, Penny is shown sipping a drink while showing off new henna tattoo encircling her hand with the caption: 'henna time!'

Rod also got his own tattoo, with an inking readying 'Celtic' on his forearm in honour of his favourite football team.

The Maggie May singer has been busy performing a string of international dates with gigs in Las Vegas, mexico and Florida all lined up.

But the pensioner's continued success story hasn't given him delusions of grandeur,

Last weekend, his wife Penny posted several Instagram shots of the couple travelling to his O2 gig by tube.

It came weeks after Sir Rod Stewart had football fans giggling into their Sunday roasts after an eccentric performance on the Scottish Cup draw.

The 72-year-old rocker smiled mischievously at the camera as he pulled out the balls of each team with tongue-in-cheek enthusiasm, before shouting out their numbers.

His antics left viewers wondering if he had enjoyed a drink or two before appearing on air, with many sharing their amusement on social media.

Sir Rod was accompanied by former Celtic defender Alan Stubbs on the fifth round draw, who appeared to be both amused and bemused by the rock star's behaviour.

However, his flamboyant attire, a dapper green blazer with a leopard print cravat, and eccentric gestures were not the only things raising eyebrows, at Airdrie's Excelsior Stadium in North Lanarkshire.

Celtic fan Stewart seemed to get so carried away that he accidentally got a six and a nine mixed up, incorrectly revealing that Greenock Morton had drawn Celtic away.

Thankfully, the tie was quickly corrected to Celtic vs Inverness moments later.

But after finding out that he had given Brendan Rodgers' team a home draw, Sir Rod cheered and gave a little first pump.

The memorable event ended with Stewart accidentally ignoring a handshake from Scottish Football Association president Alan McRae and giving a thumbs-up to the camera.
