Robert Pattinson, 27, seems to have moved on after a four-year on/off romance with his former Twilight
co-star Kristen Stewart and is taking blonde beauty Dylan Penn, his rumored girlfriend, on a romantic trip to Hawaii. A source told the Daily Star
: ''Rob wants to treat her to a break away. They have been seeing each other casually for months.'' He is still said to be in touch with former love Kristen, 23, who Rob dumped in the summer after discovering she'd had an affair with her Snow White & the Huntsman
director Rupert Sanders, but Kristen is said to be unhappy that the actor is taking Dylan on vacation.
The source added: ''Kristen is really upset that Rob has planned a romantic break with another
woman. Rob still loves Kristen but he doesn't think it can work between them, he believes they both need a fresh start. He wants to keep his options open, and he's looking forward to spending time with Dylan and getting to know her better in Hawaii.'' Robert 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.
