Top Dawg Entertainment has had a major year and they're making sure that they spread their success to those in need. The label imprint hosted their fourth annual toy drive in Watts, Calif., where Kendrick Lamar and other artists put on a free concert for fans who brought toys and donated items to the community's underprivileged youth.

During K. Dot's set, Rihanna comes out as a guest to perform "Loyalty" together off of the rapper's DAMN. album from earlier this year. The two superstars exchange lyrics for the hyped up audience, before Kendrick hands over the spotlight to Rihanna to perform a slew of her own hits.

The Anti singer does a rendition of her catchy verse on DJ Khaled's "Wild Thoughts" from this summer, as well as her verse on N.E.R.D.'s "Lemon" record that dropped earlier this fall season.

While the Compton MC also performs a slew of his own hits for the packed venue, there was even an appearance from E-40 during the two-day event in the West Coast city.
