The Real Housewives of Beverly Hills star, who blasted the former CSI: Miami star for his affair with LeAnn Rimes (who is now his current spouse) in her 2013 book Drinking & Tweeting: And Other Brandi Blunders, apparently decided there are still more secrets to spill, which she has since used as fodder for her second memoir Drinking and Dating: P.S. Social Media Is Ruining Romance.
And it's safe to say this is Glanville's not-so-subtle way of reigniting an old feud which had been seemingly laid to rest.
If you followed Brandi or LeAnn on Twitter circa 2012, then you'll recall how the archenemies once constantly fired off heated tweets to each other on the social media site, and Glanville now admits she was a tad Twitter obsessed.
"When I first discovered the benefits of technology and social media, I used it to obsess about my husband, his future wife and our children throughout our breakup and divorce," the Bravo beauty candidly writes.
"It turns out the internet can be your worst enemy," she continues later. "Especially when you spend most of your time googling medical conditions, surviving cheating, or reviewing the twitter feed of some c--t-ry music singer who likes to post countless pictures of your children #StillBugs."
And she found her obsession was an easy one to justify.
"Sure, I was 'addicted' but I rationalized that Twitter-stalking was the only way to find out what my children were doing since he [Cibrian] and I communicated solely through his assistant," she says. "When my eldest son went to the hospital with an injury after a sleepover, I only found out once his bonus mom sent out a tweet."
Glanville also seemingly addresses her headline-making hookup with Gerard Butler, which was presumably a bit embarassing for the reality star after the 300 actor was asked about the blonde beauty when she revealed he was the most famous person she'd slept with, saying, "Who's Brandi Glanville?" (he later admitted the two did sleep together).
"You should never kiss and tell, especially when it's a really famous Scottish actor and you're on live television. #KnowWhenToPleadTheFifth," she says.
To which we say: #Lessonlearned.
And of course, she couldn't pass up an opportunity to bash her ex-husband.
"He [Cibrian] screwed half of Hollywood and I'm the one with this bulls--t motherfucking label?" she writes. "I'm the crazy bitch because he couldn't keep his d--k in his pants to save his life-or, at the very least, his marriage?"
In case you weren't aware, Glanville's never been one for holding back.
But Brandi insists she's "no longer interested" in her ex-husband's life with his new wife "so religiously checking her news feed no longer interests" the former model.
Although she does seemingly mock Rimes' short stint in rehab in 2012, claiming the country crooner instead underwent treatment in "TWEE-HAB," which she defines as "a facility specializing in caring for men and women who developed an unhealthy dependency on social media."
"Example: After an unsettling month obsessing over the comments of strangers near and far, the country music singer decided to admit herself to a Los Angeles-area twee-hab facility where she met others who also struggled with expressing themselves in 140 characters or less," Brandi writes.
Let the Twitter feud begin (again).
