Famous Dex is about to be famous for the wrong thing.

The Chicago spitter -- who's signed to Rich The Kid’s Rich Forever imprint -- was caught on camera beating his girlfriend.

Singer Tish Hyman revealed the video of Dex wailing on a woman on her Instagram. Hyman said she had been letting Dex stay at her place, which Dex trashed before resorting to girl hitting.

Let this man #famousdex @famousdex stay at my place. He not only TRASHED And BROKE INTO my place. He beat this poor girl so badly. Is this the new generation of great artists that young people are looking up to? And is THIS the type of person a great company like @puma #puma chose to represent their brand. So disappointing. I hope this spreads through the Internet and shows these young people what Young Dexter is about. Thank you for hurting me young man. But you truly hurt yourself. #puma #worldstarhiphop #mediatakeout #300entertainment #theshaderoom #djakademiks

Dex addressed (and didn't deny) the video on Twitter.

Not good, Dex. Not good.
