Scheana Shay is getting vulnerable about grief, her OCD diagnosis, and aspects of her affair with actor Eddie Cibrian that she's never shared before in an exclusive excerpt from her forthcoming memoir,

Shay wasn’t the only one Cibrian was seeing outside of his marriage. He also began seeing LeAnn Rimes while still married to Glanville. After he and Glanville divorced, he married the “Can’t Fight the Moonlight” singer, 42, in 2011.

Scheana Shay made a rare comment about her affair with then-married actor Eddie Cibrian. The “Vanderpump Rules” alum recalled exactly how she fell for Cibrian, who was married to “Real Housewives of Beverly Hills” star Brandi Glanville, when she began working at a private member’s cigar lounge and restaurant in Beverly Hills, Calif., in 2006.
