Billy Magnussen has a good reason to get ripped.
The 28-year-old actor, who's rumored to be in the running to play Christian Grey in the big-screen version of Fifty Shades of Grey, was spotted entering the West Hollywood Equinox this morning ahead of a possible screen test for the highly coveted part.
A source tells E! News that Magnussen checked into the gym around 7:15 a.m. wearing a maroon shirt, gym shorts, running shoes, and sporting "longer, unkempt hair."
According to the insider, the blonde hottie skipped the weights and only did cardio exercises, which included running on the treadmill and doing an elliptical workout.
