Not everyone was excited to see the twerking tag team of Amber Rose and her new bestie Blac Chyna last week, namely Tyga.

According to TMZ, the rapper, Chyna’s ex-boyfriend and the father of her son, is tired of seeing her shake her assets. The gossip site reports that the rapper feels like she’s lost sight of caring for their 2-year-old son, King. As a result, he apparently wants to file for full custody.

The 'Make it Work’ rhymer, who is known for creating strip club anthems, reportedly lost it when Chyna was seen on Instagram in a twerk-off session with Amber.

However, Tyga claims the whole story is being fabricated and accuses TMZ of "lying." The West Coast MC took to Twitter to blast the site for involving his son in their latest report.

"@TMZ You muthaf---as is CRAZY! U wanna LIE an make s--- up on me fine. But don't Involve MY SON for ratings for Yall weak ass show. #F---Tmz," he wrote.

Tyga, who has been touring with Chris Brown and Trey Songz as of late, is gearing up to drop his long-delayed ‘The Gold Album.' He recently shared the artwork for his new album cover, which features an intricate design of a bird created by Kanye West's DONDA. The LP arrives Dec. 23.
