Michael Jackson's son Bigi is facing off against his grandmother, Katherine Jackson, in the latest legal drama for the famous family.
The 22-year-old - formerly known as Blanket - has filed to stop his grandma from spending the late King of Pop's estate funds amid their legal battle.
In documents obtained by TMZ this week, Bigi is trying to block Katherine from using money from his late father's estate to fund an appeal on a previous ruling in the complex fight.
Bigi and Katherine have been on the same page until now as they try to stop the executors of Michael's estate from making a costly transaction.
While the case has been shrouded in secrecy, it was reported that the deal they were opposing was the sale of Michael's music catalogue to Sony for $600 million.

Bigi also asked the court that they "use its best judgment" to grant Katherine reasonable attorney fees which have been incurred during the process.

He turned heads with his statuesque appearance in sports shorts and a casual t-shirt, no longer the small, shy boy who was only seven when his famous father died.

Bigi recently won the Best Drama award at the Santa Monica Film Festival for his work on Rochelles. He took on the role of director and screenwriter.

Paris is a model, actress and singer, and Prince has dabbled in acting, producing and hosting.
The "Beat It" hitmaker died on June 25 2009 from a cardiac arrest caused by a lethal combination of sedatives and anaesthetic propofol.
At the time, guardianship of his three children was given to his mom unless she was unable or unwilling to care for them in which case they would go to singer, Diana Ross.
