Uh oh ... looks like trouble may be headed to New York City on Ringer in the form of Andrew Martin's ex-wife.
The show has cast Andrea Roth (Rescue Me) as the "sexy, smart and intimidating" Catherine, according to TV Line. She's also conniving and vindictive (and no wonder, if Andrew and Siobhan really did hook up before his first marriage ended).
In an earlier episode, Bridget alluded to the fact that Juliet went to visit her mom in Miami, so something juicy must happen to bring Catherine back into town.
There's nothing we love more than a troublemaking wicked ex!
