The Worst Celebrity Feuds

Fans of "Real Housewives of Beverly Hills" might have thought it was two years or two seasons ago if they looked at Brandi Glanville's Twitter on Wednesday.

The ex-"Real Housewives of Beverly Hills" star posted a few scathing tweets about former co-star Lisa Rinna after she was briefly mentioned on Monday's airing of Bravo's reality show. The two feuded on and off during Season 5, which was Glanville's last one as a cast member.

Though Rinna has not responded to Glanville yet, she did bring up Brandi on Tuesday night's episode of the show when she called her a bully.

Your move, Rinna.
