It was ‘All ATLANTA Everythang” this weekend as Jermaine Dupri brought out the big dawgs for his So So Def 20th Anniversary weekend.

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).
