LeAnn Rimes, Eddie Cibrian Celebrate One-Year Anniversary

Famously lovey-dovey couple LeAnn Rimes and Eddie Cibrian celebrated their one-year wedding anniversary on Sunday by showing off the giant ring Rimes received from Cibrian. The singer, 29, tweeted a photo of the jewelry while also gushing throughout the day about love and astrology on the social network.

She also offered this curious insight about her relationship with the 38-year-old Cibrian: "Sitting w/ Eddie reading Kahlil Gibran. Amazing quote.... 'Is there a greater fault than being conscious of the other person's faults?'"

Rimes and Cibrian married April 22, 2011, in an intimate ceremony at a private Californian home. This is the second marriage for both parties; Rimes split from backup dancer Dean Sheremet, while Cibrian left then-wife Brandi Glanville, each allegedly to be with the other after having met on the 2009 television movie "Northern Lights."
