Lil Uzi Vert may be diminutive in stature, but he apparently knows how to land a solid punch — at least on one particular 12-year-old. While in the studio with the pre-teen rapper Matt Ox, the two threw on some boxing gloves and got down to business.

On Wednesday (August 30), an Instagram video was uploaded to a Lil Uzi fan page showing the “XO Tour Llif3” rapper wailing on the young YouTube sensation. Although it’s likely all in jest, Lil Uzi pummels Ox until he falls over on the couch.

Uzi previously showed off his boxing skills in July, which is more proof he has an affinity for the sport.

Lil Uzi released his highly anticipated sequel to 2015’s Luv Is Rage, the aptly titled Luv Is Rage 2last week. Considering Ox is in the studio with the Philly rapper, perhaps some kind of collaboration is in the works.
