Say it isn't so! Star magazine is reporting that Leonardo DiCaprio and Kate Bosworth were getting very cozy at Bardot nightclub in Hollywood on Tuesday night.

"Kate was all over Leo," says an eyewitness. "Her body language suggested that she wanted to be more that just friends and wasn't worried who saw. They spent the entire night together side by side, intimately whispering in each others ears and squeezing each other tight."

"When the club closed at 2am, Leo and Kate left with the rest of the group to keep the party going elsewhere," added the source.

Leo is infamous for taking the party to his Hollywood Hills pad. They were with a fairly large group that included Kevin Connelly, Lukas Haas and Leelee Sobieski.

Isn't Leo still with Bar Refaeli? And Kate has a man too. She's been with James Rousseau since 2006. Naughty naughty! But then again if Leo's hitting on you, it should be fair game. He's definitely on our freebie list!
