Say cheese: Camille Grammar, left, looks away from rival Kyle Richards as they posed with their Real Housewives of Beverly Hills co-star Adrienne Maloof and Taylor Armstrong at a Hollywood party last nightIt doesn't take a body language expert to figure out what's going on here.
In fact there's no hiding the mutual disdain between Real Housewives of Beverly Hills stars Camille Grammer and Kyle Richards.
The infamous foes were pictured together on a blue carpet last night at Hollywood gossip columnist Perez Hilton's birthday party.
And it seems the pair could hardly bare to look in the same direction as each other, with Camille distractedly averting her gaze away from Kyle.
Kyle, 42, and Camille, who is also 42 and the ex wife of Frasier star Kelsey Grammer, constantly fell out during the first season of their Bravo reality TV show.
In true Hollywood style, they attempted to patch things up - but their precarious relationship was constantly rocked by back-stabbing and two-faced behaviour.
