Luke Campbell worries about accidentally groping his 'Dancing On Ice' partner.

The 25-year-old boxer has been paired with Jenna Smith on the ITV figure skating show, and his fiancée Lynsey Kraanen revealed he isn't sure how to behave when he's dancing.

She said: "I really feel for [him] because he's so nervous.

"He doesn't know what to do, where to look or where to put his hands! He's so embarrassed about accidentally grabbing Jenna's boobs."

However, the 26-year-old model - who has two sons with Luke - has no fears of a blossoming romance because she knows it's just work for him.

Speaking to the Sunday Mirror newspaper, she added: "A lot of my friends asked me how I felt about Luke doing [the show] and dancing with another woman. I didn't feel anything ... it's his job.

"If he was going to cheat, then we would cheat whether he was on the show or not."

The couple welcomed second son Lincoln into the world in December (2012), and the Olympian made up for lost time having missed the birth of Leo, two, because of training.

Lynsey said: "[He] was frightened to death, bless him. But he got the towels and boiled the kettle. I don't know what I would have done without him. He was definitely my hero."
