Lookout Bar! Leonardo DiCaprio has a new admirer in actress Kate Bosworth.

Leo got extremely cozy with the 25-year-old actress, who was holding his hand and stroking his leg at Bardot 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.”

Leo was with a group of pals, including Kevin Connelly and Lukas Haas, at a table in the VIP section. They were surrounded by about 11 woman including Leelee Sobieski, but it was Kate who was snuggling up to Leo.

“Leo and Kate acted as if there was no one else in the club,” continues the source. “She was making sure his focus was solely on her and the black skintight dress she was wearing certainly helped. When the club closed at 2am, Leo and Kate left with the rest of the group to keep the party going elsewhere.”

Leo had been on and off with model Bar Refaeli since 2006; Kate had been dating James Rousseau since soon after she split with Orlando Bloom in 2006. They were seen together as recently as last week.
