Rosie O'Donnell announces birth of baby daughter

Comedian and chat show host Rosie O'Donnell announced the birth of daughter Dakota today, her first child with second wife Michelle Rounds.

O'Donnell, 50, posted a picture of herself and Rounds with their new arrival to her 587,000 Twitter followers, with the caption, "we r thrilled to announce the arrival of r daughter Dakota."

The baby girl is O'Donnell's fifth child.

The chat show host married Rounds at a quiet ceremony in June in New York. O'Donnell announced their marriage after suffering a heart attack in August.

The comedian, who hosted "The Rosie Show" on Oprah Winfrey's OWN network until it was canceled in March 2012, got engaged to Rounds in front of a studio audience in December 2011.
