Robert Pattinson is moving on from Kristen Stewart ... but not with his personal trainer, as initially reported. It turns out, the actor is aiming for another starlet with a Hollywood pedigree. Who is she?

None other than gorgeous model Dylan Penn, daughter of actor Sean Penn and actress Robin Wright. Luckily for Penn, she got all of her mom's looks -- she's a spitting image of the iconic Princess Buttercup!

Though there was speculation that Pattinson was wooing trainer Sydney Liebes, sources close to the actor deny it vehemently, saying he's head over heels for his new blond bombshell. An insider revealed, "Pattinson has trained with Liebes a few times in Harley's absence and that's it."

(Sounds like Liebes' pals just wanted a payday for those candid photos from outside the gym!)

As for Penn? It's the real deal. "They've been dating a month or two," a Pattinson pal told PEOPLE of Penn. (Say that five times fast!) "He's crazy about her."

Well, look at her. Why wouldn't he be?!
