On Thursday (Dec. 21), Top Dawg Entertainment held its 4th annual Christmas concert and toy drive and as promised, Rihanna was on hand to perform.

After performing a medley of hits including N.E.R.D's "Lemon," DJ Khaled's "Wild Thoughts" and "Bitch Better Have My Money," RiRi was joined by Kendrick Lamar to perform their collaboration, "LOYALTY."

TDE President Dave Free has previously discussed the importance of the event and why they host it in the projects. "In cities like Watts, Compton and South Central, a lot of these kids don’t get to leave their neighborhoods," he told MTV News.

He added, "They don’t get to go to these shows. They don’t have the resources, money or opportunities to be in these environments, to be submerged in music, culture and different elements. To me, that’s an important thing. That’s what I see in all these families, in their faces, that excitement."

Also in attendance for the TDE Christmas concert was Bay Area legend E-40, who performed a number of his hits. But it was Rihanna's performance with Kendrick that stole the show.
