Lil Uzi Vert caught a hacker who stole his music to try to sell online -- and the Philadelphia rapper is pissed.

It seems the unnamed hacker, who's seen in a video recorded by Lil Uzi Vert, had revenge on his mind when he took the rhymes. Uzi can be heard on video introducing the hacker, "Everybody this is Alil Nerd hiding hacker I found him cause he sold a leak song to somebody IN MY CITY. He Said I hacked your Instagram cause you ain't answer me when I tried to contact you," read a now-deleted Instagram post.

Although he appreciates the "old Super Fan s---," the 21-year-old is not feeling the love. ("I Mean Thank you but No Thanks," he wrote.) Apparently Vert isn't the only victim either -- and the hacker didn't act alone.

"Went threw his phone. Had my s--- and a lot of other RAPPERS info. DIS S--- WAS CRAZY Oh Yea He Ratted On The Fest Of Y'all IM COMING FOR YA !!! Oh yea and he be lettin these Lame ass Nobody's Have All Y'all Verses," continued the Instagram post.

In the video, Vert tells the hacker to stand up as he throws a bunch of insults towards him. After Vert calls him a "skinny ass b****," he asks him to sit back down and proceeds with a slew of more insults.

It's not looking too good for anybody involved in stealing the "Luv is Rage" rapper's music. But as Vert plots his revenge, he'll have his hands tied -- he's touring around the United States in support of his latest album, Lil Uzi Vert Vs. The World, that dropped earlier this year.

In a recent interview with Vice, the rhymer shared his plans for the future. “I'm finna be a f***ing superstar, though,” he explained. “I'ma make, like, millions. A lot of crazy s***. Just flex up. You know. Have fun.” We hear that.
