After announcing their engagement on Monday, Rosie O’Donnell and Michelle Rounds gave the world a look at the impressive ring that the talk show host gave her ladylove.

Rosie posted a photo of the sparkler on Twitter on Monday night accompanied by the caption, “so so so happy.”

Stars including Marlee Matlin and Bravo executive and “Watch What Happens Live” host Andy Cohen congratulated the star on her big news.

Rosie responded, Tweeting, “i am very happy.”

As previously reported on AccessHolllywood.com, Rosie’s rep confirmed to Access that the two became engaged several weeks ago and will continue to split their time between New York City and Chicago, where Rosie films her Oprah Winfrey Network talk show, “The Rosie Show.”

Rosie and Michelle first went public with their romance at the red carpet for the Building Dreams for Kids Gala in New York City in September.

The talk show host was with Kelli Carpenter, a television marketing executive, from 2004-2007.

The pair have four children together — Parker, Chelsea and Blake, who were all adopted and Vivienne Rose, who Kelli gave birth to in 2002.
