Robert Pattinson and Natalie Portman reportedly vowed to keep in touch following a flirty introduction at a pre-Oscars party last month.

As Entertainmentwise previously reported, Rob was seen working his British charm on Paris Hilton at the Rick Yorn and Patrick Weitzell bash, and Natalie Portman in the same evening at the Vanity Fair party.

But it seems that the Star Wars actress made more of lasting impression than the blonde heiress, with Rob hanging on her every word.

A source tells Now magazine, "He seemed to be enjoying every minute of it.

"She dominated his attention for most of the evening."

Meanwhile, Paris seems unphased by her British brush-off, and has already moved onto The Hills star Doug Reinhart.

Hmmm, Robert or Doug? We know who we'd prefer.
