UNDER SUSPICION

Leann Rimes worries hubby Eddie Cibrian is getting a little too close to co-star Rachel Bilson.

If there’s anyone who knows about Eddie Cibrian’s wandering eye, it’s Leann Rimes, whose relationship with him began with an affair. And the country star, 35, is taking no chances with her husband filming the new series Take Two in Vancouver, Canada, with single co-star Rachel Bilson. “Leann went with Eddie to Vancouver,” an insider exclusively tells Life & Style. “She’s been monitoring his every move, and she hasn’t made it a secret that she thinks Eddie and Rachel have gotten a little cozy for her liking.” The precedent has been set: Back in 2009, Leann and Eddie co-starred in Northern Lights and began seeing each other while he was married to Brandi Glanville (and she was married to Dean Sheremet). And Rachel, 36, split from Hayden Christensen this past September after a decade together. “Leann says she has plenty of reason to be worried,” the insider adds. “Rachel is gorgeous, and her chemistry with Eddie is off the charts.” The former star of The O.C. posted a flirty Instagram video in March of Eddie, 44, shoving Altoids in his mouth, and Leann wasn’t amused. “She saw red flags,” the insider says, “when she watched Eddie mugging for the camera while Rachel giggled like a smitten schoolgirl.” So Leann is being a helicopter wife. “She’s not being subtle at all about it,” the insider says. “Eddie and Rachel know exactly what’s up. Leann is watching them.”
