Alicia Keys served up a girl power treat at the Bet Awards in Los Angeles on Tuesday night when she performed with Swv, En Vogue and Tlc's Chili and T-Boz.

Live collaborations were very much in vogue at the ceremony with Lil' Kim joining Keyshia Cole onstage and rap heavyweights Ludacris, Flo Rida, Rick Ross, DJ Khaled and Big Boi joining T-Pain for his circus-style performance.

But the night's collaborative live highlight came towards the end of the ceremony, when Nelly performed with Jermaine Dupri and Fergie.

Meanwhile, Best Male R+B Artist Chris Brown and Ciara teamed up for a sexy rain dance onstage at the Shrine Auditorium.

Lifetime Achievement recipient Al Green capped a tribute medley by leading sing-along versions of his love standards Let's Stay Together and Love + Happiness.

Usher and Rihanna also stunned with live performances, and rap's million selling miracle, Lil Wayne teamed up with T-Pain to close out the show.
