We were all happy to hear that Robert Pattinson had finally moved on from Kristen Stewart.

The actor is said to be dating Dylan Penn - but the romance is already proving difficult.

Radar Online reported the other day that Robert Pattinson showed up with a mystery brunette at some party on the weekend and they were all over each other. Gossip Cop – at press time 10am Wednesday 25 September – still hasn’t posted Pattinson’s publicist side of the story (a denial).

He was also photographed on the weekend with a ‘mystery brunette at the gym.

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 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!

The pair partied at the Viper Room in West Hollywood together on Sept.
