Sienna Miller, who has been previously linked to Hayden Christensen and P. Diddy, has now got her eyes set on a new man.

The blonde was recently seen passionately kissed Bryan Ferry's model son, Isaac Ferry, at the BAFTAs after-party.

Sienna arrived at the ceremony alone but was later seen getting cozy with the Roxy Music legend's son at London club Boujis where they partied until 5 a.m.

A source told Britain's Daily Mirror newspaper, "Sienna was really hot for her new man. They were holding hands and he was whispering in her ear. There was a lot of chemistry between them. They moved into the back room that was cordoned off for select BAFTA guests. They were kissing until 4 a.m. before coming out and joining the rest of the party."

21-year-old Isaac and 25-year-old Sienna first met when they were being photographed at the same studio. The actress is said to have immediately clicked with Isaac, and was eager to introduce him to movie mogul Harry Weinstein at Sunday night's party. But Isaac played it cool and flirted with other guests.

A source revealed, "At one point Isaac was looking over at this gorgeous model and Sienna looked a little jealous."
