Katherine Heigl, T.R. Knight Leaving GREY'S, Says Costar

Katherine Heigl and T.R. Knight will soon take off their scrubs for good, their Grey's Anatomy costar confirms. Us Weekly released the scoop earlier today.

When Us Weekly asked James Pickens Jr. (a.k.a. Grey's Dr. Richard Webber) on February 7 if Heigl is leaving the medical drama, he said, "Yes, she is." And he continued, "Wherever Katherine goes, I wish her nothing but the best."

Following Heigl, 30, out the door?

Her outspoken BFF, Knight, 35. "He's going too," Pickens told Us at the NAACP Awards luncheon in Beverly Hills. "He just wanted to pursue other career paths."

"He complains to Katherine all the time," a set source has said of Knight (with Heigl). "The energy on set will be much better when he's gone."

Both Heigl's and Knight's reps had no comment, and ABC and ABC Studios could not confirm the departures.
