Young Jeezy kicked off BET Hip-Hop Awards weekend and celebrated his birthday all at the same time with a very intimate event — only 50 people were invited — at radio personality Frank Ski‘s new restaurant and night lounge last night in Atlanta.

The rapper, who turned 33 years old Wednesday night (Sep 28), partied it up with the likes of Ne-Yo, Ludacris, Jermaine Dupri, Atlanta Mayor Kasim Reed and more.

Jeezy even showed up to the soiree, sponsored by Ciroc and Red Bull, with a new armpiece, model Jasmine Sanders (who dated Chris Brown in the past). And our homie FreddyO was on hand to capture all of the action!

Jermaine Dupri is hoping to lead the production team behind R&B singer Mariah Carey‘s upcoming 13th studio album and tells Rap-Up.com that he’s in the early stages of recording Mimi’s follow-up to her 2009 album Memoirs of an Imperfect Angel.

“We started last week and we don’t take long when we get in, so hopefully a single before the end of the year,” he told Rap-Up.com. Bryan-Michael Cox and Johnta Austin are also involved with Mimi’s new music.

Meanwhile, Mariah is also working on a Christmas album and did a shoot for it with photographer to the stars David LaChapelle.

While the details of their personal, romantic relationship is unknown, Jermaine Dupri and Janet Jackson are teaming up with Bryan Michael Cox for JJ’s next album, the follow up to Discipline, released in 2008.

“I’m producing Janet’s album with Jermaine and it’s going to be hot,” B. Cox told Rap-Up.com at Tricky Stewart’s pre-Grammy party last Friday. “That’s all I can say so far.” His producing partner Kendrick “WyldCard” Dean also chimed in, adding, “Some great collabos on there,” but didn’t disclose further details.

Janet has been in the studio with Rodney “Darkchild” Jerkins working on her 11th studio album, due this year on A&M Records.

Peep this video of Usher, Jermaine Dupri, Johnta Austin, Bryan Michael Cox and JD’s assistant Tyrone, collectively known as “The Ocean 5 Crew,” clowning Christina Milian for rocking that blonde wig at the Hawks/Cavaliers game in ATL, in addition to talking about the Chris Brown and Rihanna situation, calling the young teens a modern day Ike & Tina. The video was originally posted to Jermaine Dupri’s YouTube account as a part of his “Living the Life” vlog series, but he has since then removed it. Luckily, the CNN of Urban Media (aka World Star Hip Hop) grabbed it and upped it to their site.

Halfway through the video, JD mentions them “having drinks” before filming, which is pretty obvious, especially with Usher shouting and acting a fool through most of the video. Even though the things they were saying were pretty effed up, we had no choice but to laugh. We’re sorry, but the sh*t was funny!
