"I met this guy (the one with the mic) 14 years ago today and it was the best thing that ever happened to me, no contest," Parsons captioned the pic of Spiewak singing. "One of his greatest gifts to me is that he no longer takes me to sing karaoke. Also, I believe this was a selfie with an actual camera, as our phones couldn't do that back then hahaha! #todd #anniversary."

Parsons also opened up about his relationship with Spiewak at the GLESN Respect Awards in 2013.

"I've never considered myself an activist," he said during his acceptance speech. "I've never considered my relationship with Todd to be an act of activism. Rather simply, it's an act of love -- coffee in the morning, going to work, washing the clothes, taking the dogs out -- a regular life, boring love."
