Amanda Holden has admitted that she is worried about an unstable Katie Price, after encountering her strange behaviour at a recent showbiz party.

Earlier this month Amanda met Katie at a party in London’s Mandarin Oriental hotel, thrown by her Britain’s Got Talent colleague Piers Morgan.

Amanda revealed that after she tried to convince Alan Sugar to hire her for next year’s Apprentice and serenaded her in the ladies toilet, Katie Price started pulling provocative poses as if in a Playboy shoot in the middle of the dance floor.

Holden told The News Of The World:

Later, in the ladies, Katie grabs my hands and suddenly starts belting out Bryan Adams’ Heaven. It’s a little bizarre but, I have to say, that girl’s got a voice! A few drinks later, we’re having photos taken and Katie begins posing provocatively on the floor as if she’s on a calendar shoot. Lily Allen looks on horrified and bursts into tears. “Somebody needs to help her, this is awful to watch,” she sobs, so I put my arm around her and try to calm her down.

I share Lily’s concerns, though. Before I leave, I see Katie singing to the entire room. She seems so vulnerable. I feel sad, but it’s not my place to rescue her.
