But it seems the confession wasn't enough for the judge presiding over his case.
On Thursday the judge stopped all electronic devices from being used in the courtroom and conference rooms as she feared the rapper wasn't taking the case seriously enough, TMZ reports.
Judge Ann Nevins warned: "There is nothing funny going on here. This is all very serious business.
"I am not trying to impede on anyone's right to exercise free speech. But I would appreciate it if we can keep the tone of this case very serious.
"You have all been advised. This is not funny.
"I want to make this very clear, that I am discouraging the use of social media to comment on this case, especially when parties are in a courtroom or in the conference room."
Despite her harsh warning, the judge praised the Candy Shop singer for making progress with the case.
She said: "By being present Mr. Jackson has made significant strides toward getting this case moving."
Speaking afterwards, 50 vowed to heed the judge's words.
He said: "Instagram? Nah, that's not me anymore."
The case will return to court in May, when details of the rapper's new business deals will be disclosed, his lawyer said.
50 previously claimed his frequent cash-filled social media posts were made in a bid to preserve his reputation.
"What I say and what I do on social media has a direct impact on my music sales and the viewership on my television shows."
