Actor Robert Pattinson has sparked rumours he is dating model Imogen Ker after the two were spotted on a couple of recent dates together.

The Twilight star and Ker were reportedly spotted holding hands as they exited Hollywood hotspot Good Times at Davey Wayne's last month (Apr14), and they enjoyed a dinner date at another popular celebrity hang-out, the Little Door, a week later.

Pattinson and Ker, who is friends with the actor's ex-girlfriend Kristen Stewart, were reportedly introduced by mutual pal Dakota Fanning.

The 28-year-old hunk split from Stewart last year (13) after trying to save their relationship following her brief fling with director Rupert Sanders.

He was most recently linked to Sean Penn's model daughter Dylan, but she has denied ongoing rumours she's dating Pattinson.
