Robert Pattinson is enjoying a blossoming romance with Dylan Penn.

The Twilight actor appeared to have moved on from Kristen Stewart when he took blonde beauty Dylan - who is Sean Penn's daughter - to a book launch party in Los Angeles last week, and a source has now confirmed that the pair are definitely seeing each other.

While the couple aren't calling each other "boyfriend and girlfriend" yet, Robert is reportedly attracted to the 22-year-old star's intelligence. "[They] appear to be well suited for each other. Dylan doesn't want to be famous. She doesn't want to be an actress. She wants to be a screenwriter. She's been approached about acting work, but it's not her thing. You won't see her becoming a regular at Bootsy Bellows," an insider said.

The British actor was first spotted out in public with Dylan in September at the Chateau Marmont in West Hollywood, and Robert is said to be smitten. Rumors were rife the 27-year-old hunk had rekindled his romance with Kristen last week after they met up for several hours in Los Angeles. However, the former couple are now thought to have met up as friends.
