Ringer Casts Madchen Amick Siobhan's Ex-Bestie

A rich socialite like Siobhan Martin (Sarah Michelle Gellar) was bound to have more friends (or at least, frenemies) than her architect, Gemma Butler.

So it's no surprise that Ringer will introduce another person in Siobhan's sphere — a former friend to be played by Madchen Amick (Twin Peaks, Gossip Girl), reports TV Line.

Amick will play Greer Sheridan, a “confident, sexy and strong-willed” fellow socialite who was once very close to Siobhan. When twin sister Bridget works with her on a charity event, she tries to discover exactly what happened to cause a rift between the former besties.

Look for Greer to show up in episode 11!
