Robert Pattinson is taking Dylan Penn to Hawaii

'Twilight' actor Robert Pattinson is taking his rumoured new girlfriend Dylan Penn on a romantic break to Hawaii.

The 27-year-old actor is said to have moved on after a four-year on-off romance with his 'Twilight' co-star Kristen Stewart and is taking blonde beauty Dylan, who is actor Sean Penn's daughter, on a three-day luxury vacation next month, reported Daily Star.

"Rob wants to treat her to a break away. They have been seeing each other casually for months," a source said.

Pattinson and Dylan were first seen in public together in September at the Chateau Marmont in West Hollywood and also attended a book launch party in Los Angeles last week.
