Lil Twist, a Young Money rapper and Justin Bieber’s BFF, has been accused of beating and pantsing, former Nickelodeon star Chris Massey on Friday afternoon (Nov. 7).

According to TMZ, Twist and a group of friends were at Massey’s older brother’s apartment in Los Angeles when an argument occurred. The site reports that Twist, along with others, beat Massey up, and then “after pounding him, one source says Twist and his buds doled out some humiliation by pulling Chris’ pants off.”

Twist, who last month, vented on Twitter about his grievances with his management over unreleased music, was also arrested for DUI last year.

Massey was reportedly taken to a hospital for treatment, and authorities will investigate the situation.
