Charlotte Church has banned boyfriend Gavin Henson from speaking to other women.
Rugby star Henson used to chat to girls during nights out.
But he told Hello! Magazine: “I’d been used to going out and having a little attention from girls, but with Charlotte this wasn’t allowed.
“She’d have a little tantrum about it, so I said ‘Okay, I won’t speak to any girls ever again then.’ So that’s that settled.”
Church, 20, admitted: “I’m really jealous and he knows that I just can’t help it. It’s a bad quality to have, most unattractive.”
The former Voice Of An Angel, now hosting her own Channel 4 show, has been dating Henson for 18 months.
Her curvy figure is under constant attention but Church said she would slim down if Henson asked her to.
“I’d only try to lose weight if he thought I should. I know that’s not a very feminist thing to say, being the independent woman I am, but it matters to me what Gavin thinks,” she said. “I come over as quite feisty but I’m a complete pushover with Gav.”
Henson said he is a healthy eater while Church is a sugar addict.
“She’s hyper and it’s because of her diet. One minute she’s up and the next she’s crashing down. If she hasn’t had her sugar intake by 12am each day she thinks she’s dying,” he said.
Church admitted: “I’ll be there eating bars of chocolate and biscuits and he’ll be eating a carrot.”
Welsh rugby ace Henson, 24, is obsessed with his appearance, claiming that being good-looking improves his game.
He said: “I like to look in the mirror before a game and if I’m looking good it will give me that extra edge and make me feel a little better about myself. It’s all part of the routine, shaving my legs, putting on fake tan and doing my hair.”
Henson said his rugby bosses were critical of his celebrity lifestyle but he insisted: “Basically, I don’t really care what they think.”
