LeAnn Rimes organic sunglasses singer lunch blonde

LeAnn Rimes was all smiles when we snapped her grabbing lunch at Kreation in Santa Monica this afternoon, and strangely enough, it looks like her homewrecking ways have brought two unlikely people closer together: her jilted hubby Deane Sheremet and Eddie Cibrian's soon-to-be ex-wife Brandi Glanville!

A source tells Us Weekly that the less famous exes have been supporting each other while Eddie and LeAnn go about flaunting their adulterous relationship in public. "[Eddie and Brandi] put the pieces together about the last few months, and they're developing a good friendship through this." A pal close to Deane adds, "They're the ones who understand what the other is feeling."

Hmm, maybe they'll shack up? Or at the very least Deane can be her personal shopper, right?
