Is this where it all started?
The pair partied at the Viper Room in West Hollywood together on Sept. 7, Rob in his usual ensemble of pants, T-shirt and baseball cap and Dylan, with her blond hair pulled back, bearing a striking resemblance to mom Robin Wright.
After watching Mickey Avalon at the Viper Room they reportedly hit Chateau Marmont, which is just down the road, to cap off the night with snacks and drinks.
Despite reports that the pair are dating, however, we're continuing to hear that it would be premature to label them as anything more than friends at this point.
A source says that the two—who, incidentally, met through Rob's ex, Kristen Stewart—have hung out a few times but are not steadily dating.
Meanwhile, Rob's been out to Chateau a few nights this week with groups that did not include the 22-year-old Dylan.
So for now, we can lump Dylan in with the various other women whom Rob is not romancing, including Riley Keough, Sia and trainer Sydney Liebes. (Though Liebes does have a special relationship with the 27-year-old actor—she's whipping him into shape!)
And though he rarely hurts for companionship, Pattinson, who broke up with Stewart in May after about three years of dating, does venture out alone at times. He headed to the gym all by himself just yesterday!
The British actor most recently reteamed with Cosmopolis director David Cronenberg on the Hollywood satire Maps to the Stars, which was shooting in L.A. over the summer.
