Britney Spears has made a choice in who she wants to replace her father Jamie as her conservator.

On Monday, the 39-year-old pop star's attorney Mathew Rosengart filed a request to remove the singer's father Jamie as her conservator and replace him with Jason Rubin.

The move came a week after Rosengart announced that he and his associates planned to help Spears remove her father from his position – a stance that has garnered growing support in recent weeks after the star's bombshell testimony last month in which she lobbied intense allegations against her father.

At the time, Spears said she was "afraid" of her father and claimed that he had been abusive with his power as conservator. Since then, she's stated that she hopes to someday charge Jamie with "conservatorship abuse."
