Nicki Minaj is gearing up for a verbal showdown with Kevin Federline following the release of his controversial memoir, “You Thought You Knew.”

The 42-year-old “Barbie World” artist didn’t mince words when addressing Federline, Britney Spears’ former husband, after Spears issued a statement criticizing Federline’s new book.

“KEVIN FEDERLINE B–H WHEN I CATCH U,” Minaj reportedly tweeted, according to TMZ. Although the tweet has since been deleted, it clearly signaled her disapproval.

In her own statement, pop icon Britney Spears, 43, expressed frustration with Federline, whom she was married to from September 2004 until July 2007. Spears accused him of “constant gaslighting” in the wake of his memoir’s release. The book reportedly alleges instances of child abuse, infidelity with one of her backup dancers, and drug use on Spears’ part.

“The constant gaslighting from my ex-husband is extremely hurtful and exhausting,” Spears shared on the social media platform X on Wednesday.

“I have always pleaded and screamed to have a life with my boys,” she continued. “Relationships with teenage boys is complex. I have felt demoralized by this situation and have always asked and almost begged for them to be a part of my life.”

Spears — who shares sons Sean Preston, 20, and Jayden James, 19, with Federline, 47– went on to allege that her sons “have always witnessed the lack of respect shown by own [sic] father for me” and claimed that they “need to take responsibility for themselves” in adulthood.

Spears has not yet addressed the cheating allegation specifically. Though, her former dancer Teresa Espinosa — who is named as the alleged hookup in Federline’s book — released a message in defense of the Princess of Pop.

“I feel blessed to have shared the stage with her all over the world. She allowed me to live my dreams as a professional dancer and eventually asked me to choreograph the ‘Outrageous’ music video, which was never fully completed because she hurt her knee on set,” Espinosa told her followers on Thursday.

“And so here’s my take: NO ONE will EVER know what it’s been like to walk second in her shoes,” she concluded.

Spears’ rep has also slammed Federline’s forthcoming book, telling Page Six in a statement: “With news from Kevin’s book breaking, once again, he and others are profiting off her. Sadly, it comes after child support has ended with Kevin.”

According to Spears’ rep, “All she cares about are her kids … and their well-being during this sensationalism.”

Kevin Federline’s “You Thought You Knew” will be released on Oct. 21.
