The 50 Cent lawsuit against Tia Kemp seeks at least $6 million in damages over social media posts that allegedly targeted his 14-year-old son, Sire Jackson. The rapper, whose real name is Curtis Jackson, filed the federal case in Los Angeles on Monday, October 26, accusing Kemp of publishing false and humiliating claims about the teenager. He later spoke out on Instagram about adults targeting minors.
According to the complaint, Kemp, whose full name is Tiallondra Kemp, repeatedly made claims about Sire’s development, including alleging that he is on the autism spectrum. She also made sexually degrading remarks about the boy’s mother, Daphne Joy, and suggested her behavior during pregnancy caused a medical condition, Jackson’s attorneys allege. No verified medical information has been presented to support those allegations.
The 50 Cent lawsuit accuses Kemp of defamation, invasion of privacy and intentional infliction of emotional distress. Jackson filed on behalf of Sire, who is identified by his initials in the paperwork because he is a minor. His attorneys contend that Kemp was not discussing a public controversy involving the child but using him to hurt his father.
The California case is separate from a petition Jackson filed the same day in Miami-Dade County, Florida. That filing seeks a temporary injunction barring Kemp from stalking, cyberstalking, or harassing Sire, followed by a longer-lasting court order after a hearing. His lawyers cite four online publications within six days, including remarks allegedly made during an October 25 interview about Sire’s speech and development.
The 50 Cent lawsuit followed an earlier effort to stop the posts without going to court. Attorneys sent Kemp a cease-and-desist letter demanding that she remove the material and stop posting about the teenager. Instead, according to the filings, she shared part of the letter online and dismissed the warning. The legal team argues that the alleged conduct has embarrassed Sire and caused emotional distress.
As the legal fight made headlines, the G-Unit founder addressed the controversy on Instagram with a warning about bullying minors. His message moved beyond his family dispute, pointing to the consequences harmful posts can have for young people.
“It’s not ok to bully minors on line, kids have killed them selves over things people have said about them. That gangster granny act is not gonna work no white flags.”
The 50 Cent lawsuit also addresses how autism was used in the posts. Jackson criticized the use of autism as an insult in a separate Instagram statement, adding that he has friends with children on the spectrum. His reference to a “gangster granny” appeared directed at Kemp. The complaint argues that autism should not be used to humiliate a child, regardless of whether a diagnosis exists.
The dispute followed an earlier confrontation involving Kemp’s 21-year-old son with Rick Ross, William Roberts III. William reported that he was threatened and struck with a gun near Bethune-Cookman University in Daytona Beach on October 11. A suspect was later arrested and charged, and he has pleaded not guilty. Jackson mocked the incident in social media posts and discussed helping the accused man with bail. There has been no confirmation that he paid the bond.
Kemp responded by criticizing Jackson and posting about Sire and Daphne Joy. The 50 Cent lawsuit alleges her remarks escalated into repeated personal attacks on the teenager, including claims about his ability to speak. It also objects to online images that allegedly placed Sire alongside sexually explicit material involving an adult woman. Those are allegations in the filings, not judicial findings.
Kemp has rejected Jackson’s legal pressure publicly. In a TikTok response, she mocked the rapper’s name and insisted he could not bully her. She had not provided a formal court response in the reporting available Tuesday, October 27, and no judge had determined whether the disputed posts constituted defamation or unlawful harassment.
The two cases seek different outcomes. The California action requests financial damages, while the Florida petition asks the court to restrict specific conduct. Whether Jackson wins either request depends on evidence and the applicable legal standards. For now, the 50 Cent lawsuit brings the latest clash involving his long-running rivalry with Ross into federal court, with his son’s treatment at the center of the complaint.
