Going by Brandi Glanville, the Little Tramp wasn't Charlie Chaplin.
And that's pretty par for the course, with Eddie Cibrian's ex-wife sometimes not having a problem with his new wife, while other times she's never met a tramp joke she didn't like.
So, while Glanville told reporters this week at a signing for her book, Drinking & Tweeting and Other Brandi Blunders, that she's "expecting a cease-and-desist," how are Rimes and Cibrian really dealing with Glanville's stream of cracks at their expense?
"They do not focus or think about Brandi," a source close to the couple exclusively tells E! News. "They are living their lives and have moved on.
"Eddie just wants to focus on being a good father to the boys," the source adds. "The children come first. I hope they are not being affected in any way."
Glanville has said that her two sons with Cibrian are what's most important to her, as well, saying at her signing that she hopes her ex doesn't cheat on Rimes because she doesn't want their kids going through another divorce.
"It is unfortunate how things ended [between Cibrian and Glanville]," says our insider, "but that is in the past now. And no matter what happened then, it does not justify Brandi's actions now. People make mistakes, she just needs to move on."
"I usually don't engage," Rimes said of the rejuvenated war of words on Jimmy Kimmel Live last month, "but there comes a time when you're just like, 'Screw you, that's it,' and that's all you wanna say, and you're like, 'I'm done with this now,' for, like, another three months."
