Natalie Portman has a crush on Robert Pattinson. The 27-year-old actress - who split from boyfriend Devendra Banhart last September and has also been romantically linked to Maroon 5's Adam Levine and multi-billionaire Nat Rothschild - was spotted flirting with the young "Twilight" star at Vanity Fair's Oscar party on Sunday.

An onlooker said: "The two totally flirted outside on the patio. Natalie is used to getting what she wants and she dominated Robert's attentions for most of the evening."

John Mayer was "all over" a mystery woman at the weekend, it has been claimed.

The musician, who is rumored to be dating Jennifer Aniston, reportedly canoodled with a beautiful blonde stranger while partying with Maroon 5 frontman Adam Levine in a New York club on Friday night.
