It was reported yesterday that Keo Reid had featured in a number of 'gay-for-pay' clips but he is said to be 'beyond devastated' by the new revelations.
Lorna, 18, has been dating sports therapist Keo, 25, for six months and was left 'embarrassed' this week when the first clips surfaced.
A source told the Mirror: "She's such a sweet girl and she'll hate her family and everyone else finding out about this."
The more explicit clips have left Keo devastated, but his boss is standing by him.
"Keo's just a regular guy," the businessman, who wishes to remain unnamed, said. "I know he has a chequered past but this has no affected his job.
"I have been contacted by some idiots since the story came out but thankfully most people are blissfully unaware.

"People need to trust Keo and have confidence in him as a sports therapist and he just wants all of this to disappear.
"He's beyond devastated. It's horrible."
Despite the sexual clips, Keo's boss insists he's not gay. He continued: "He's a tough, straight lad from a building site and although he has nothing against homosexuality, he is not gay.
"When you're in a situation of having no money, you could go down the road of breaking into houses, stealing cars or mugging old ladies, or you could use your initiative and just survive.
"He's not made a decision one day to be a porn actor because of the thrill of it. He's been in a position where has had to earn money."
It hasn't been confirmed whether or not Lorna – who plays Abi Branning on the BBC One soap – will be standing by Keo, who has refused to comment on the stories.
