Chace Crawford will never date a co-star.

The actor - whose fellow ‘Gossip Girl’ stars Blake Lively and Penn Badgley are in a relationship - wants to keep his personal and professional life separate.

He said: ” ‘Gossip Girl’ creator Josh Schwartz told me to avoid at all costs dating a co-star. We get to shoot in New York and have that as our playground and do the insane things that we get to be a part of. There’s a part of me that wants to share that.

“But I’m having fun living the bachelor life right now. It’s a good time to be single.”

Chace also dismissed rumours he moved out of the apartment he shared with co-star Ed Westwick because the pair are no longer friends.

He explained to Wonderland magazine: “Frat time’s over. I’m just turned 24, I need my own space. I don’t know why anyone wants to read about the condition of our apartment. It cracks me up. It was actually pretty immaculate.

“I’m OCD [Obsessive Compulsive Disorder]. I had a maid come twice a month. We have a few roof deck parties from time to time, but that’s all.”
