"Real Housewives of Beverly Hills" star Brandi Glanville is preparing for the launch of her new book and a new report claims that the reality TV star's long time enemy LeAnn Rimes will likely be furious over the book's content.
Glanville, who has been at war with Rimes ever since the troubled singer had an affair with her her former husband Eddie Cibrian in 2009, will reveal explosive details about the affair in the book entitled "Drinking and Tweeting: And Other Brandi Blunders."
"She details the lies, affair, hurt and how it all went down. There are things [LeAnn] does not want her family and fans to know and soon they will," a source told Life & Style magazine. "There are tons that no one knows that went on, and Brandi holds nothing back."
Rimes, 30, who was also married at the time of the affair, eventually went on to marry Cibrian, who shares two sons with Glanville.
"[LeAnn] has painted the picture that it was just out of her control and how she fell in love with Eddie and it was done respectfully but that could not be further from the truth," the source continued.
"Things are gonna get worse [for LeAnn] before they get better. LeAnn won't be happy," the insider said.
The country singer has received widespread backlash from fans since admitting to the affair, and in a recent interview with "Entertainment Tonight's" Nancy O'Dell, Rimes admitted suicide crossed her mind at least once, though she would never take her own life.
"Of course, I think anybody could," Rimes said when asked about whether she contemplated suicide. "I think any smart person would know that it is always a possibility that you could always get that sad and deep. I worried that was a possibility [but] I know I would never."
The singer, who checked into rehab in August, also admitted that she has feared Cibrian will cheat on her like he did Glanville, according to Daily Mail.
"I would be ignorant to say, and everyone else would think I am a liar if I didn't say yes, and I have at times," Rimes said before admitting that he too has the same concerns about her.
"Speaking for him, I would actually say that's creeped into his [mind]," she continued. "I think we've been very honest and open with that to 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 to each other."
