Robert Pattinson tried to keep a low profile as he stepped out in Los Angeles last night. But, we couldn't help but notice the mystery blonde walking in front of him as they left hotspot Little Door Friday at 1 a.m..

While it's not clear if the unidentified woman is just a pal or something more, the duo rushed to an awaiting vehicle as soon as they headed out after a night of fun.

Apparently, this girl is not such a mystery after all. We found out that her name is Imogen Ker and apparently they both had an amazing date night according to an eyewitness at The Little Door.

"Rob was here with a pretty blonde. It was just the two of them and they sat outside in the patio for a long time," the eyewitness revealed to HollywoodLife.com exclusively. "They had dinner and drinks. They looked like they were having a good time. They left close to 1am."

The Twilight star wore casual garb for their evening out, sporting a black jacket, a white t-shirt, jeans and a low scruffy beard, while the blonde kept it casual as well, rocking a black tank top and ripped jeans.

Pattinson was last spotted hanging out with Katy Perry during Coachella, fueling rumors that he was dating the "Dark Horse" crooner, or her stylist friend Cleo Wade (both turned out not to be true).

Although the thesp was spotted looking somewhat clean cut during his night out Friday, Pattinson got dirty recently for the cover of French magazine, Premiere, rocking colorful face paint and a floral-graphic sweatshirt.

The cover is for the mag's special Cannes Film Festival issue, which was fitting, considering Pattinson's next big film, Maps to the Stars, will premiere there when the fest begins May 14.

It was recently announced that the 27-year-old actor dropped out of the upcoming indie thriller Mission: Blacklist as he did not have sufficient time to prepare for the demanding role in the film, according to TheWrap.

Rob just wrapped work on the movie Life and he will be heading to Cannes this month to premiere two films.
