Hello, Heather!

For its seventh season, the Real Housewives of Orange County has added a brunette to its mix: Heather Dubrow.

A new bio at Bravo's official website reports that dark-haired Dubrow is a former actress now married to prominent Newport Beach, Calif. plastic surgeon Terry Dubrow. A stay-at-home mom, Heather has four kids with Dr. Terry: twins Nicholas and Maximillia, 8, Katarina, 5 and Collette, 10 months.

One fun fact about this new castmember? Despite her hubby's profession, she's "never had plastic surgery" other than Botox and filler, the bio boasts.

In the first episodes of season seven, East Coast girl Heather (who introduces the OC girls to "champagne bowling" and art classes) bonds with Tamra Barney -- and clashes with Alexis Bellino.

Joining castmates Bellino, Barney, Vicki Gunvalson and Gretchen Rossi, Dubrow is a replacement of sorts for housewife Peggy Tanous, who departed after just one season following season six.
