Also on Twitter this week, Glanville has been promoting Dean Sheremet's appearance on her Podcast series, Brandi Glanville Unfiltered. As fans well know, Sheremet was married to LeAnn Rimes when she engaged in a 2009 affair with Glanville's former husband on the set of their Lifetime movie, Northern Lights.

Glanville even addressed the possibility of dating Sheremet, revealing that wasn't a possibility because he's already married.

Famously Single will air this spring on the E! Network. A premiere date has not yet been revealed.
