Desiigner is facing a defamation lawsuit after accusing an Instagram businesswoman of conducting “college scams” on social media. The one-hit rapper is being sued for writing an Instagram post accusing Jessica Brown of scamming his sister.

Brown claims she helped the “Panda” rapper’s sister, Siera Selby, land a place in prestigious HBCU Howard University in Washington, D.C. through her company College Gurl, which educates students on how to pay for their higher education.

Brown also allegedly arranged for Siera to have access to a storage unit while at the school, but the youngster ended up dropping out, leaving some of her belongings behind in the locker.

Brown reportedly reached out to Siera to return her items, but Siera told her she no longer wanted them. Later, Brown was put on blast by Siera’s famous big brother, reports

In a since-deleted post on Instagram last August, Desiigner is accused of telling his 1.7 million followers:

“This girl is a fraud. Tried to scam me into paying for my sister to get into Howard University and now she is trying to hold my sisters [sic] belongings. Please stay away from her and her college scams!!”

He also tagged Brown’s company profile in the post, and now she is suing the 20-year-old Brooklyn native, real name Sidney Royel Selby III, for defamation and invasion of privacy. It’s unclear how much she is seeking in damages.
