Robert Pattinson and Dylan Penn haven't made their "relationship" official yet, but sources confirm they are definitely dating each other.

Observers claim that romance has been brewing between the Twilight star and Sean Penn's daughter. Like Rob, Dylan feels the same when it comes to her work.

"Dylan doesn't want to be famous," the source said to E! Online. "She doesn't want to be an actress. She wants to be a screenwriter. She's been approached about acting work, but it's not her thing."

Rob was first spotted with Dylan in September and the two hanging have been hanging out ever since, sparked off dating rumors. Life & Style magazine later reported that the two were seen getting cozy at the Viper Room in Los Angeles. A source said the couple couldn't keep their hands off each other the entire time and spent the night chatting.   

"They were touchy-feely and very flirtatious. There was a level of comfort there," the source said. "You could tell they've hung out a few times." 

According to reports, it was Dylan who helped Rob through his trying times when ex-flame Kristen Stewart cheated on him with director Rupert Sanders.

Rumors of them dating came to a standstill when Rob reunited with Kristen briefly over a week ago. Reports of his romance with Dylan surfaced again after they were spotted together during a celebration for Angie Banicki's travel memoir "30 Before 30". They arrived at the event separately, but sources said that the two were flirting with each other.

"The two chatted and flirted inside," a witness told People. "They were a little cautious, making sure people noticed they did not come together. Rob was being social. Girls were chatting him up. He and Dylan were very kind and chatty but definitely made a point to keep things a bit separated."
