ROSIE O'DONNELL has become a mother for the fifth time.

The 50-year-old TV star - who has children Parker, 17, Chelsea, 15, Blake, 13, and 10-year-old Vivienne with ex-wife Kelli Carpenter - announced yesterday (09.01.13) that she and wife Michelle Rounds have adopted a baby girl named Dakota.

Posting a picture of the baby on her Instagram page, she wrote:''We are thrilled to announce the arrival of our daughter Dakota.''

The little girl weighed in at 5lb 5oz and Rosie's representative said ''moms and baby are healthy and happy''.

Rosie - who married Michelle in a secret ceremony last June - revealed last year that her then-fiancée had sought help from fertility specialists in a bid to get pregnant.

She said last January: ''She's trying to get pregnant.''

Soon after the couple married, Michelle was diagnosed with desmoid tumors, a rare cancer-like disease.

Two months later, Rosie suffered a heart attack.

The pair were planning a bigger wedding for later this year when they are both back to full health.

The talk show host blogged recently: ''When we are both well enough, [we] will have the wedding of our dreams surrounded by those we cherish.

''[We are] thankful for the love and support so many have given us during these trying times.''
