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.
They were joined by their co-stars Adrienne Maloof and Taylor Armstrong at last night Blue Ball party for Perez.
However fellow cast members Lisa Vanderpump and Kim Richards, Kyle's sister, were not in attendance.
Kim and Kyle - who were also constantly at loggerheads during the show - are the aunties of socialite and heiress Paris Hilton.
