A British mother filmed romping with a man on a Ryanair flight said she is 'mortified' that a bit of drunken fun has gone viral.

Tracey Bolton, 39, was filmed straddling 31-year-old Shaun Edmondson, who left his heavily pregnant fiancee at home to go on a stag party.

Horrified passengers on board the flight to Ibiza looked on as the wild pair gyrated and Shaun asked holidaymakers for a condom.

Café owner Tracey, a mother of three, had been drinking at Manchester airport before romping with Shaun aboard the packed plane, friends claim.

Shocked passengers filmed the couple as they had moved back and forth in the Shaun's seat.

Tracey, from Colne, Lancashire, told a friend: 'I am absolutely mortified. What started as a bit of drunken madness has gone worldwide.

'I am horrified but absolutely nothing happened. I haven't stopped crying since I saw it. I am so embarrassed,' she added.

Friend Kirsty Lawton, also of Colne, told The Sun: 'Nothing really happened. She did a fully clothed lapdance for a laugh, no sexy time occurred.

'The pair of them were being daft and it was all for a laugh.

'They didn't know one another, as if you would do that with anyone let alone a stranger.'

Mr Edmonsdon has returned home following the stag do.

A family source told MailOnline: 'From what I understand, he was supposed to be back by now - and he might well be.

'But he has completely gone into hiding since this has all kicked off. He could still even be over there.

'Apparently none of his family, or his girlfriend have been able get in touch with him.

'He's gone absolutely AWOL. I don't believe it was actually his stag do, I think it was for one of his mates.'

Passengers watched as Ms Bolton clambered on top of Mr Edmondson and they began to gyrate an hour into the flight to the party island.

A friend said Mr Edmondson is known as a 'ladies' man' despite being engaged to fiancee 25-year-old Miss Ross.

'That's just a random woman he's with, they didn't know each other before the day,' the friend said.

'He doesn't seem to be too bothered he has left his six-months pregnant wife-to-be at home while he cavorts with random strangers.'

Mr Edmondson works as a chef at the upmarket Lyth Valley Country Inn in Kendal, a family pub which is owned by his relatives.

It is understood that Mr Edmondson's fiancee Miss Jenna, who is originally from Canada and has been with him for six years, is aware of the video.

Passenger Kieran Williams, 21, from Preston, Lancashire, said he was astonished to see their raunchy antics an hour into the flight on the budget airline.

'I heard them talking about it but I thought they were joking. The guy was shouting, 'Anyone got a jelly?' meaning condom.

'We all laughed but then ten minutes later they actually did it. They seemed so drunk, they brought a lot of attention to themselves.

'You could see the girl taking off her pants and he pulled his trousers off. She started riding him.

'I had to get my phone out. I have never seen anything like that.'

Tight lipped: Mr Edmondson, pictured, hasn't spoken to his family about the incident, a relative said - adding: 'He has completely gone into hiding since this has all kicked off.'

He said: 'They were starting and stopping but it was completely obvious what was going on. We all had a good laugh about it. It was pretty funny.'

A Ryanair spokesman said: 'We are looking into this matter.

'We will not tolerate unruly, disruptive or inappropriate behaviour at any time and any passengers who appear to behave in an unacceptable manner may be liable for further sanctions.'
