Katherine Heigl & TR Knight: Grey's Reunion!

Katherine Heigl cracks up as she and hubby Josh Kelley head into a theater to catch a movie on Sunday (May 2) in Glendale, Calif.

The 31-year-old actress brought along friend and former Grey’s Anatomy co-star T.R. Knight!

Patrick Dempsey recently spoke to the New Zealand Herald about how Grey’s has changed over the years.

“I think there’s been three different shows,” Patrick shared. “There was the original cast, and [then] the departure of Isaiah Washington ended that. Then with T.R. going and now with Katie sadly going, it feels like it’s been three different types of shows.”
