Rosie O'Donnell sure knows how to keep her lady happy!

Hours after Us Weekly broke news that the talk show host and girlfriend Michelle Rounds were set to wed, O'Donnell shared photographic evidence via Twitter.

"So so so happy," O'Donnell, 49, tweeted with a photo of a beaming Rounds showing off an enormous diamond engagement ring.

O'Donnell announced her happy news to the Rosie Show studio audience on Friday, telling fans they plan on tying the knot over the Christmas holiday. It's a quick courtship, for sure: She and Rounds, an NYC headhunter, debuted as a public in September at a Rosie Theater Kids Gala in the Big Apple.

O'Donnell has four children with ex-wife Kelli Carpenter, whom she married in 2007. They split three years later. O'Donnell dated mother of six Tracy Kachtick-Anders for one year before calling it quits last winter.
