The Real Housewives of Orange County is adding two new ladies to the mix for its upcoming season — and they both have "shady pasts," Radar reports.

The new cast members are Meghan King Edmonds and Katie Chadwick Hamilton, both of whom are married to professional baseball players. (Edmonds is married to retired MLB star Jim Edmonds and Hamilton is married to Josh Hamilton.)

There's already a potential rivalry brewing between Edmonds and Shannon Beador. Fans may remember that Edmonds attended Heather Dubrow's hoedown party last season, and flirted with Beador's husband David.

Chadwick Hamilton, meanwhile, comes from a family with a "rocky past that will come to light," Radar reports.

Returning for Season 10 are Beador, DuBrow, Vicki Gunvalson, Tamra Judge andElizabeth "Lizzie" Rovsek. Original cast member Jeana Keough reportedly will also appear in some episodes.
