Given their history, it's not too surprising LeAnn Rimes is wary of Eddie Cibrian cheating on her, although she believes they can avoid both scandal and heartbreak this time.
Asked if that possibility worries her, the country star, 30, told Entertainment Tonight's Nancy O'Dell that "Everyone else would think I am a liar if I didn't say yes, and I have at times."
"It's definitely creeped into my mind, as it would anyone's."
"We've been very honest and open with each other, and our conversations about it have only made me understand how much he actually cares, as much as I do, about being faithful."
"Where I'm at in my relationship with Eddie, [it's not] in the front of my mind."
The duo started dating in 2009 on the set of Lifetime's Northern Lights while still married to other people - Rimes to Dean Sheremet and Eddie to Brandi Glanville.
Glanville recently sat down and confronted another Eddie Cibrian mistresses, waitress Scheana Marie, during episodes of The Real Housewives of Beverly Hills and Vanderpump Rules.
Think LeAnn can look forward to similar philandering? Or did he get it all out of his system in pursuit of a relationship in which he will truly be faithful and happy?
