Grey's Anatomy's "George," T.R. Knight is getting cozy with boyfriend Mark Cornelson.

The couple has been dating since February.

Katherine Heigl and new husband Josh Kelley paid tribute to their dead brother and sister at their Christmas wedding.

The "Knocked Up" star and the "Only You" singer exchanged vows in front of friends and family in a "winter wonderland" on December 23, but the ceremony also included a musical tribute to Katherine's brother, Jason, who died in 1986, and Josh's sister who died as a baby.
