(Cover) - EN Showbiz - Rosie O'Donnell was "really proud" to show off her girlfriend backstage at her new talk show.

The popular TV host is dating Michelle Rounds, who she met in a Starbucks caf earlier this year. Her new series The Rosie Show premiered yesterday evening on Oprah Winfrey's OWN network. The star previously presented The Rosie O'Donnell Show, which aired between 1996 and 2002.

Rosie, 49, was supported by Michelle backstage at Harpo Studios, where, according to onlookers, she fit in perfectly.

"Rosie brought Michelle to the studio on Friday and gave her a tour," a source at The Rosie Show told US Weekly.

"She is very attractive and friendly. Rosie was really proud and showing her off, and introducing her as 'my partner' - which was a little surprising, since they are newly dating.

"They seem really happy though and were holding hands and Rosie had a lot of fun showing her around the show."

Rosie and Michelle celebrated the premiere with a three-hour dinner at Chicago's Paris Club. They were joined by Rosie's daughter, Chelsea.

Rosie has four children with ex-wife Kelli Carpenter, who she married in 2007. They split three years later.

Rosie and Michelle made their first public outing together at last month's Rosie Theater Kids Gala in New York City. (C) Cover Media
