Twilight star Robert Pattinson was a busy man on Oscar night.

After presenting during the telecast, he hit the Vanity Fair after-party, where he was spotted having a long, deep conversation with Natalie Portman, according to E! News.

Later in the night, Pattinson apparently shared another hour-long confab with Paris Hilton at a different party.

Spies from the Mirror say Hilton even dragged Pattinson out into the garden for some private time. But by 5 a.m., the young hunk was on his way to the airport to head to Japan.

Busy night, indeed.
