While all eyes focused on Chelsea Clinton‘s nuptials, much of hip-hop’s royalty was celebrating T.I.‘s wedding to longtime girlfriend Tameka “Tiny” Cottle. Joining the couple at Cameo in Miami Beach Saturday night were Rihanna, Nelly, Ashanti, Ke$ha and Jermaine Dupri. A spy told us, “Usher kept sending dozens of bottles of champagne with sparklers to the new couple, while Jamie Foxx serenaded them by rapping over the deejay and shouting out, ‘The bride and groom.’ ” T.I. and Tiny followed up their courthouse wedding with a reception on Star Island.
