Dylan Penn has split from Steven R. McQueen.

The 22-year-old model - who is the daughter of Sean Penn and his ex-wife Robin Wright - has decided to call time on her brief relationship with the 'Vampire Diaries' star, who is legendary late actor Steve McQueen's grandson, but they are still friends.

A source told E! News: ''I think it just fizzled.''

The blonde beauty was first spotted on a dinner date with the 25-year-old actor in November and the pair were accompanied by her famous father and Jon Hamm following the premiere of Sean's film, 'The Secret Life of Walter Mitty.'

However, the duo only went public with their relationship when Dylan brought Steven as her date to her father's Help Haiti Home Gala in Los Angeles last month.

The blonde beauty, who recently landed a fashion campaign with Gap, came to public attention in September when she was romantically linked with 'Twilight' hunk Robert Pattinson.

But an insider insisted her romance with the 27-year-old British actor was merely a fling, saying: ''Dylan is a fun chick, whatever she had with Pattinson was very brief if at all.''
