More than four years after LeAnn Rimes and Eddie Cibrian embarked on their affair -- and countless passive-agressive tweets later -- Brandi Glanville is finally admitting she just might have a problem. The outspoken Real Housewives of Beverly Hills star admits to having an unhealthy obsession with Rimes and Cibrian in her new book, Drinking & Dating: P.S. Social Media Is Ruining Romance, and only Breaking Celebrity News has all the details.

In the very first chapter of her bombshell book, a follow-up to last year's Drinking & Tweeting, Glanville makes it clear for the first time that the very reason she got involved with Twitter to begin with was to track Rimes and Cibrian's movements.

"When I first discovered the benefits of technology and social media," she admits, "I used it to obsess about my husband, his future wife, and our children throughout the breakup and divorce."
