RHOBH's Adrienne Maloof and Paul Nassif Separating After Nine Years Of Marriage

After nine years of marriage, three kids and two seasons of the reality show Real Housewives of Beverly Hills, hotel mogul Adrienne Maloof and her plastic surgeon hubby Paul Nassif are filing for legal separation this week, according to several reports.

The couple fought constantly during the first two seasons of the hit show - but always with a tinge of humor. The pair aren't the first of the Housewives cast to split -- Camille Grammer and actor husband Kelsey divorced just after the beginning of the first season and Taylor Armstrong separated from her husband Russell just before he took his own life in August 2011.

Maloof and Nassif have three sons - Gavin and twins Colin and Christian, who were rarely seen on-camera during the series. Kim and Kyle Richards, Lisa VanderPump, Taylor Armstrong and Brandi Glanville will be joined by Yolanda Hadid this season - she's the fourth wife of Grammy-winning music producer David Foster. Camille Grammer will not return.
