Jim Parsons celebrates 14 years with boyfriend Todd Spiewak in throwback selfie

'Big Bang Theory' actor Jim Parsons and his boyfriend of 14 years Todd Spiewak recently commemorated their anniversary in a memorable throwback selfie.

The 43-year-old actor and comedian gushed about Spiewak on Instagram, where he wrote, "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."

The picture shows the couple posing for the camera from a memorable karaoke session. While Spiewak looks like he was wholeheartedly singing into the mic, young Parsons has his blue eyes sparkling with innocence.

"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," the 'Normal Heart' actor added to the caption.

Parsons has been open about his relationship with graphic designer Spiewak, both in interviews and on social media.

During the TV star's 2013 'Emmy Awards' acceptance speech, he concluded by saying, "To my favorite person on the planet, Todd Spiewak."

Earlier, when asked about marriage by Ellen DeGeneres on her show back in May 2014, Parsons revealed that there is no rush to tie the knot because he felt he had not been "enthusiastic enough" about it.
