Looks like someone had a blast.
T.R. Knight, 40, married his boyfriend this past Friday in New York and Knight's former "Grey's Anatomy" co-star Katherine Heigl, 34, posted some candid photos inside the event.
Heigl, who wore a red lace dress, first posted a pic yesterday on Twitter of her getting ready to head out to the wedding. "My bestie Chey and I perfecting our disenchanted fashionista pose before attending a wedding in upstate NY," the tweet read.
Next, the "27 Dresses" star posted another pic, this time from the wedding itself, which included another past "Grey's" star Kate Walsh.
"Having the time of my life at said wedding with @katewalsh @joshbkelley Kate's amazing fella Chris & my girl Chey!" the caption read above a photo booth pic of the crew giving goofy faces for the camera.
Heigl and Knight worked together on the show from 2005 to 2009, with Knight earning an Emmy nomination in 2007 for Outstanding Supporting Actor.
The just-married man is currently playing the role of Mercutio in an off-Broadway run of "Romeo & Juliet."
