Update (9/27/13): Us Weekly confirmed that Robert Pattinson is indeed dating Dylan Penn. A source tells the mag that she visited him on a film set recently, even before the cozy date described below, and that she was his date at a friend's September 21 birthday party. Still no word from reps for either party, though, so we're not declaring them official... yet!

Original story (9/25/13):

We have yet another potential Bella to Robert Pattinson's Edward — if you believe a new report that is — and his latest rumored date has serious Tinseltown pedigree.

Robert broke off his four-year relationship to Twilight co-star Kristen Stewart earlier this year, and now Life & Style reports that he was spotted getting intimate with Dylan Penn at L.A.'s Viper Room on September 7.

Dylan is a drop-dead gorgeous, 22-year-old model — and she happens to be the daughter of two-time Oscar winner Sean Penn and his ex-wife, House of Cards star Robin Wright (aka She of the Awesome Haircut).

"They were touchy-feely and very flirtatious. There was a level of comfort there," a source tells Life & Style of the reported date. "You could tell they’ve hung out a few times."

The duo then reportedly went to the bougie Chateau Marmont for fries and drinks before heading with a group to his home, where, a witness claims, "They went into his kitchen, and he put his arms around her. Then he was kissing her neck and talking all lovey-dovey."

An insider tells the outlet that Sean has high standards for anyone who dates his daughter, so Rob might wanna be on his best behavior if he really is wooing Dylan. (This is the same guy who went to jail for assaulting a photographer during his marriage to Madonna.)

Fun fact: Sean Penn and Robert Pattinson would have been co-stars if Sean had been cast in 2011's Water for Elephants. The part Sean was circling eventually went to Christoph Waltz.

Do you believe the rumor? Or do you think this is just post-K.Stew gossip mongering? Cast your vote below.
