Glanville, 40, has two sons (Mason, 9, and Jake, 5) with ex-husband, actor Eddie Cibrian, now married to LeAnn Rimes. (Her feud with Rimes -- and rift with Cibrian, who had an affair with the country singer -- is an ongoing conversation topic on RHOBH; the brash, outspoken reality star joined the series in season two, clashing instantly with sisters Kim and Kyle Richards. For now, there's a truce.)

Glanville, who can currently be seen sparring with Adrienne Maloof on Beverly Hills' season three, is publishing her debut book (on dating and divorce) in February.
