Rihanna Gives Sneak Peek Of Topless Photoshoot, Kicks It With ATL Celebs At Her Concert

It's a big week forRihannaas she jetted fromsome major playtime in Miamiwhere she also had a Diamonds World Tour concert stop...to Atlanta for another celeb-filled tour stop and a topless photoshoot. And, she just set a new Billboard Record for Pop music.

Deets and pics inside...

Gabrielle Union, who's in the ATL filming her new BET show"Being Mary Jane," and Ludacris were just two of the celebs backstage at last Rih Rih's Diamonds tour stop.

She saw some folks before she hit the stage, and plenty afterwards as well:

After switching into some cutoff shorts and a tank, Rih posed it up with the OMG Girlz.

And Tiny& Shakeenah were in on the pics too of course.

T.I.P. stopped by to wish his"Live Your Life" collabo partner good luck.

Jermaine Dupri brought his gorge daughter Shaniah along to meet Rihanna.

Monyetta Shaw, Ne-Yo's finacee, chilled out in Rih's dressing room and put on some makeup.

Gabby& Chanel Iman, who's been traveling around with Rih's opener A$AP Rocky as his new boo thang, got kissy in the audience.

And Rih's assistant Jen and stylist got in on it all.

And it was the topless pic from a photoshoot earlier in the day that had people wondering what the"Pour It Up" chick was up to next.  Chick's skin is perfection.  Hot.

And y'all already know what else she hit up after the show...Magic City strip club. Peep some video below:

More good news for the pop diva--she just became the first artist in the 20-year history ofBillboard's NielsenBDS-based Pop Songs radio airplay chart to tally 10 No. 1s, as"Stay," featuring Mikky Ekko, went to #1. She was previously tied with her good friend Katy Perry at 9, but it looks like somebody's Rih-written history. Congrats!
