When "The Real Housewives of Orange County" returns for Season 7, there will be new blood -- and a new hair color -- in the mix.
Brunette beauty Heather Dubrow joins blonde bombshells Vicki Gunvalson, Tamra Barney, Gretchen Rossi and Alexis Bellino for a new season of Bravo drama starting Tues., Feb. 7 at 9 p.m. ET.
Heather, a former actress, is now a stay-at-home mother of four and wife to a prominent Newport Beach plastic surgeon.
Season 7 kicks off with Vicki in the process of divorcing Donn, putting her house on the market and introducing the other "Real Housewives" to Brooks, her new boyfriend. Meanwhile, Gretchen joins the Pussycat Dolls, Tamra takes her relationship with Eddie to a new level and Alexis gets a job as a local news correspondent.
In a press release, Bravo says Tamra and Gretchen grow closer, putting a strain on their other relationships.
