Claim: Chris Brown collaborated with T-Pain.

`` Shawty Get Loose '' is the third single from hip hop artist Lil Mama 's debut album , VYP : Voice of the Young People . The single is the remix version , where it features Chris Brown singing the chorus , and T-Pain rapping on the second verse . In the original , T-Pain originally sings the chorus , while Lil Mama raps on the second verse . Instead of T-Pain using the Auto-Tune effect , Chris Brown uses it , like he did in his other collaboration with T-Pain , `` Kiss Kiss '' .
