Gossip Girl star Ed Westwick has again denied rumors he is dating co-star Chace Crawford - insisting he finds reports "amusing".

The actors have been subjected to speculation they are dating, but Westwick insist they just live together, and nothing more.

He says, "I just laugh them off.

"What are you going to do? People who know me and Chace and the cast know that we are all great friends. And that's the extent of it all. Those things that go around are just amusing to us, really."

Meanwhile, Crawford's spokesman says, "These endless rumors are absolutely untrue."
