MSNBC anchor Thomas Roberts and his fiance on Sunday released official engagement photos.

Roberts and Patrick Abner, of Merck Pharmaceuticals' HIV/AIDS division, will marry next month in Manhattan. The pair have been together 12 years and announced their engagement via Twitter on June 25, 2011, one day after gay marriage was legalized in New York.

In their engagement photograph, the men are dressed casually – stonewashed jeans and blue suede shoes – along with their mixed labs Riley and Roxy.

The 39-year-old Roberts, who came out gay in 2006, previously told The New York Observer that he does not believe that being the first news anchor to marry a person of the same sex will hurt his career at MSNBC.

“I am not objective when it comes to equality,” said Thomas. “And that means for all. I want it for you, for me, for everybody … It's written in the our Constitution: life, liberty and pursuit of happiness, and what's wrong with talking about that? Nothing.”
