It was a super A-list weekend, with one very big question: What was she doing with Leonardo DiCaprio on Saturday night?
First, on Friday, Paris and Todd hit director Joel Silver's birthday dinner, where power couples such as Tom Hanks & Rita Wilson, Barbra Streisand & James Brolin, and Robert Downey Jr.. and his wife Susan were all on hand to help him celebrate.
Then Paris, Todd and Leo all did dinner at Nobu in Malibu, along with Lukas Haas and Joseph Gordon-Levitt.
Why this particular mix—three movie stars, an heiress and The Hangover director? Apparently the dinner wasn't to talk business, according to a source.
"It was just for fun," they tell me.
"Everyone was saying what a great couple Paris and Todd made," a source says, adding that they were both very affectionate throughout the evening.
Paris' little sister seems to agree. "Nicky usually doesn't like the guys Paris dates but she love Todd and thinks he's a great guy," a source close to Paris says.
