Robert Pattinson may have just become the frontrunner to play Christian Grey in the upcoming "Fifty Shades of Grey" adaptation, if the guest list for a recent party at his Los Angeles home is any indication.

Pattinson recently partied with E.L. James, the author of the series, who showed up with actress Heather Graham to the weekend soiree. While there were plenty of stars at the bash, James's presence was particularly notable, fueling speculation that Pattinson had sewn up the much-coveted role of the bondage fanatic.

The actor would be a fitting choice for the part, considering his tangential connection to the steamy series. "Fifty Shades" was originally written as fan fiction about the "Twilight" series, the film adaptation of which starred Pattinson as Edward Cullen, the very character who inspired Grey.

Many of Hollywood's hottest hunks have reportedly been circling the part, including Ryan Gosling, Zac Efron, Armie Hammer, and Alex Pettyfer. But considering the film's British pedigree -- James, director Sam Taylor-Johnson, and writer Kelly Marcel all hail from across the pond -- it'd be appropriate for a fellow Brit to win the role, and Pattinson fits that bill.

As always, this news should be considered only a rumor until official word comes from the filmmakers. But considering how badly most of Hollywood wants in on the adaptation -- director Gus Van Sant reportedly shot test footage in a bid to win the directing job -- we'd say Pattinson's invitation to James shows he's at the very least interested. Stay tuned.
