After the So So Def concert ended with the likes of Lil Jon, Usher Raymond, Ludacris, Jay-Z, Young Jeezy, Monica and Mariah Carey, it was a all VIP celebration at Atlanta’s Compound night club.

The only person missing was T.I…. but then again maybe the shade Tip threw during ASCAP’s Living Legends Dinner put a spark up under JD’s “A”zz to get this whole anniversary thing poppin (just a thought).
