Rosie O’Donnell revealed to the audience at a taping of her talk show that she and girlfriend Michelle Rounds are engaged and plan to get married around Christmas. If this is the first time you’ve heard Rounds’ name don’t beat yourself up too much for failing to keep up with Rosie’s love life. Just three months ago their love affair began, like many great romances, when Rosie spotted Michelle in a Starbucks and misjudged her sexual orientation and her age by about a decade. In an interview with Nightline, Rosie said, “I thought she was a 28-year-old heterosexual girl, because that’s what she looked like to me. And she’s a 40-year-old gay woman. My gaydar was way off!” Rosie’s been Tweeting cute photos of Michelle with captions like “happy — in love,” and she already has a retort for those who say she’s moving too fast. In October she snapped at a nosy reporter, “C’mon, I’m 49 and I’m gay.” [People, People]
