While revealing how she snogged the Angels singer, Kerry said: "I didn't have sex with him. I could have. But I wasn't ready to. I regret it now though." The former Atomic Kitten's night with Robbie happened shortly after Brian walked out on her in 2004.
On an episode of Kerry's MTV One show, Kerry confesses to a pal about the smooch - and says she now wishes she would have slept with Robbie. Kerry says: "I have snogged Robbie Williams - it's official. I've snogged Robbie Williams - I can't believe I have just said that on camera.
"I have snogged Robbie Williams - aaaah! I phoned my mum and said mum, Robbie's coming round. She was like 'get in the shower, shave your legs, shave your arm pits. Before I answered the door I want 'aaaahaaaha' then 'alright Rob, come on in. And he stripped off. I didn't know what to do. I started dusting. But I didn't sleep with him. I didn't have sex with him. I could have! But I wasn't ready to. I regret it now ,though."
