'Grey's Anatomy' actor T.R. Knight celebrates 10-year anniversary in adorable post

In the midst of celebrity divorces and breakups, T.R. Knight's relationship is still going steady.

The "Grey's Anatomy" alum took to Instagram on Tuesday to celebrate a major milestone he reached with his husband, ballet dancer and writer Patrick Leahy.

Alongside a photo of the couple with beautiful green scenery and blue skies as the backdrop, Knight wrote, "Ten years ago, @bridgeteverett @zshaffer1 and @jasoneagan made meeting this magnificent human possible."

"My goal for the next ten? Keep trying to deserve him," he finished, adding that the photo was from one of his "favorite adventures" with Leahy, and the next day they found their golden pup, Traveler.

The 47-year-old actor, who portrayed Dr. George O'Malley in the longtime ABC medical drama, has been married to Leahy since 2013.

Tons of the couple's A-list celebrity friends poured out their support for the couple in the comments including fellow "Grey's Anatomy" star Ellen Pompeo, who wrote, "Love you guys," followed by a series of red heart emojis.

Actresses Lena Waithe, Bitsie Tulloch and Brigett Everett also left endearing comments on the post as well.
