After months of rumors, LeAnn Rimes and Eddie Cibrian have made it official. The country singer’s rep told People magazine exclusively on Monday that “they were engaged over the holidays and are very happy.” An insider told the magazine that 28-year-old Rimes and her 37-year-old fiancé spent Christmas at home in Los Angeles, celebrating their impending nuptials with family and close friends. Rimes revealed her ring in Malibu on the beach on Monday with Cibrian. The insider says the ring features a 5-carat oval diamond and it was reportedly designed by Cibrian with the help of his childhood friend, jeweler Brent Polacheck. Rimes and Cibrian met while filming Northern Lights, a 2009 Lifetime original movie, though they were both married to other people at the time.
