Leo & Kate Bosworth Celebrate All Night At GQ Magazine's Party

Leonardo DiCaprio, celebrating GQ Magazine's annual Men of the Year party at West Hollywood's Chateau Marmont. Surrounded by a table of models, the actor spent much of the night chatting with Kate Bosworth and sipping on a Grey Goose cocktail. "They were really close together and acted super flirty," says an onlooker. "They just kept getting closer as the night went on." But the party didn't end there: The pair – joined by DiCaprio's BFF Lukas Haas and pal Kevin Connolly – also stopped by Bardot Hollywood, where they settled into a table in the back lounge area and closed down the hot spot.

Gwyneth Paltrow and her husband Chris Martin, dining at Dallas's swanky Al Biernat's steakhouse while Martin's band, Coldplay, was in town to perform. "They were relaxing, talking and laughing," says Brad Fuller, general manager at the famous Dallas hot spot. "It was like any other married couple's dinner out without the kids. They were cozy and enjoying a night out by themselves." The couple tucked into a back booth for their seafood dinner. For dessert Paltrow ordered coconut cream pie, while her hubby picked the molten chocolate cake. Then things got even sweeter: The pair loved their dinner so much, Martin promised to send tickets over to the restaurant's manager. Says Fuller: "I had no idea I'd get Coldplay tickets from Chris Martin himself!"
