The worst: LeAnn Rimes broke up Eddie Cibrian's marriage to Brandi Glanville and refers to herself as "bonus mom" to her two stepsons. But Glanville thinks Rimes has overstepped her bounds in "really inappropriate" ways. Khloe Kardashian was, until recently, stepmom to Lamar Odom's two kids with an ex-girlfriend—and that ex-girlfriend once said of Kardashian, "I don't know if she's good maternally." Speaking of stepmoms related to the Kardashians, Kim, Khloe, Kourtney, and Rob sued their stepmom Ellen Pearson for allegedly stealing family writings and photos, which she then allegedly sold to a publishing company. Gisele Bundchen said she considers hubby Tom Brady's son from his marriage to Bridget Moynahan "my child." Needless to say, Moynahan was not happy. Former NFL player Kordell Stewart recently filed for divorce from Real Housewives of Atlanta star Porsha Stewart, and he reportedly said she so neglected his son, her stepson, he had to hire a nanny. To cheer yourself up, click to see the 6 best—including one who wrote to a judge on her troubled stepson's behalf.
