EXCLUSIVE PHOTOS - Rob Pattinson Hosts Fifty Shades Of Grey Author E.L. James At Star-Studded Bash

Is R-Patz angling for another blockbuster role?!

Robert Pattinson threw a birthday party for director Nicholas Jarecki on Saturday night at his Los Feliz pad, and some of the hippest people in Hollywood were in attendance, including Fifty Shades of Grey author E.L. James!

Rumors have been swirling for some time now that the British actor was in the lead to play Christian Grey in the film adaptation of the erotic novel, and from the looks of it, he's making sure he rubs elbows with the right people!

An X17online photographer tells us:

"There were so many Hollywood types there. It was definitely a party for Rob to meet girls but it was also a time to do business. There were older industry people there- Rob was definitely making connections."

Although former love Kristen Stewart was noticeably absent, other guests included Ellen Page, Michelle Rodriquez, Moby, and Heather Graham, who arrived with James and tweeted the below picture from the inside the bash with the caption, "A fun party looking at the super moon with Moby @thelittleidiot and EL James @E_L_James."

Sounds like quite the soiree! Guess we will have to wait and see if this Twilight hunk's networking paid off!
