Atlanta, the "Hollywood" of the south, lived up to its name last night with epic performances at Philips Arena from a few of your favorite old school and new school acts. The arena was packed to capacity for the sold out show hosted by V-103 for the 40th Anniversary of Winterfest.

R&B crooner Keith Sweat was tapped to perform some of his soulful ballads. He rocked out with Grammy Award winning singer-songwriter Teddy Riley to his track “Just Got Paid.” Then, he surprised fans with a special performance with Johnny Gill (above) for a LSG reunion. RIP Gerald Levert.

90s R&B group Silk had everyone on their feet singing their classic hit “Meeting In My Bedroom.”

90s group Bell Biv DeVoe brought that signature R&B sound as they performed their catalog of hits.

Rapper/reality star Nelly hit the stage to perform some of his throwback tracks. He brought out soulful singing group Jagged Edge to perform "Where The Party At."

R&B crooner/actor Tyrese also gave a soulful performance.

Backstage....

Singer-songwriter Keri Hilson was spotted snapping it up with Keith Sweat before he hit the stage.

Good friends Tamika Scott from Xscape and Lil G from Silk were all smiles backstage.

Rapper/actor Ludacris made his rounds backstage at the show.

"Love & Hip Hop: Atlanta" star Stevie J is still in Atlanta after celebrating his daughter Eva's 6th birthday a few days ago. He was in the mix backstage.

In the audience...

LeToya Luckett was trying to get kissy with her boyfriend Rob Hill Sr., but was hilariously photobombed by Luda, his wife Eudoxie and Keri Hilson. Ha! Fun times.

Peep a few clips from the show below:

Monica brought her hubby/free agent Shannon Brown, their adorable baby girl Laiyah and her handsome sons Rocko and Romelo to work with her. The R&B singer signed autographs at Julian Scott Boutique for her recently released album CODE RED.

So adorbs!
