The comedian, 50, adopted a baby girl with wife Michelle Rounds, her rep confirms to Us Weekly. The tot weighed 5 pounds, 5 ounces when she was born on Saturday, Jan. 5. "Moms and baby are healthy and happy," her rep says.
"We are thrilled to announce the arrival of our daughter Dakota," O'Donnell shared on Instagram Jan. 9, along with a snapshot of herself, Rounds, and their little bundle of joy. "With love and thanks -- AMEN."
Dakota is O'Donnell's fifth child; the former talk show host also shares kids Parker, Chelsea, Blake, and Vivienne with ex-wife Kelli Carpenter.
O'Donnell and Rounds announced their engagement in December 2011. They married six months later in a secret, no-frills ceremony on June 9, 2012, shortly after Rounds was diagnosed with desmoid tumors, an extremely rare, cancer-like disease.
O'Donnell herself suffered a health crisis in August, when she had a heart attack and had to be treated in the intensive care unit, but both women are on the mend now and hope to have a bigger wedding later this year.
"When we are both well enough, [we] will have the wedding of our dreams surrounded by those we cherish," the former View co-host blogged. "[We are] thankful for the love and support so many have given us during these trying times."
