Former Nickelodeon star Chris Massey was hospitalized yesterday after he was beaten up and pantsed. Young Money rapper Lil Twist is a suspect in the assault.

According to TMZ, Chris, Twist and Massey's younger brother, actor and rapper Kyle Massey, were among those hanging out at Kyle's LA apartment yesterday afternoon. An argument broke out and Twist and his crew gave Chris a beat down which required a trip to the emergency room.

To add insult to injury, they then pulled down Chris's pants. (How TMZ knows this detail, we are not entirely sure.  Did Chris arrive at the hospital without pants?)

Cops are investigating, but so far Twist has not been arrested.

Twist, who might be most famous for his association with Canadian terror Justin Bieber, has previously been busted for drugs and DUI. The 21-year old is also among the artists who have taken to social media to express frustration with Young Money.
