Sam Thompson has opened up about what happened between him and Amelia Lily after Celebrity Big Brother.
The pair enjoyed a brief fling on the show which carried on outside the house - for a while.
Recently Amelia revealed the pair no longer talk and now Sam has admitted he treated the X Factor singer "badly".
Speaking after signing up for the new series of E4's Celebs Go Dating, Sam said: "I'm back up. I make no qualms about it, I didn’t treat Amelia Lily very well. I didn’t treat my ex-girlfriend very well hence why she dumped me.
“I had been down there on the floor for a bit and I think it's time to pick myself up a bit. All my family and friends are like 'dude just get on with it' and everyone else is."
He added to The Sun newspaper: "I have never done anything like this before in my life.
“So I don't know how it's going to go."
Discussing their relationship last month, Amelia told new! magazine: "We don't speak. Everything's fine, but I guess it was just the wrong timing. He's a lovely guy."
Asked if they were still friends, Amelia replied: "I don't know! I think so. As far as I'm aware, we are. Like, he's really busy being in Made In Chelsea and I'm really busy doing my thing.
"But I always said that I would have time for him in my life."
Celebs Go Dating will return to E4 next year.
Alongside Sam, other celebs signed up include his fellow MiC star Ollie Locke and TOWIE's Gemma Collins.
