NEW YORK -- 50 Cent is a boss, so he'll boss you around and you'll like it! The G-Unit general was throwing out orders to people who weren't even there on Friday afternoon at the Nokia Theater in Times Square. The entire G-Unit got onstage for a brief performance of their stint for "A Night for Vets: An MTV Concert for the BRAVE" (check out their full performance when the show airs Friday night at 10 p.m.).

"I have the savoir-faire," 50 rapped. "I'm the reason everybody's here/ I say, 'Get up!'/ I make it hot, I make it hot in here/ Your feet hurtin', I really don't care/ I said, 'Get up!'

I want see you, I want to see you move/ And get all into the groove/ I said, 'Get up!' "

The concert will be the very first time 50 will perform "Get Up" on television, and he was definitely excited. The Unit's practice was a quick 15 minutes, and after a couple of minor tweaks, everyone felt they were ready for showtime. Ludacris (who rehearsed Wednesday), Kanye West, Hinder, Saving Abel and others will also perform for the concert.

After the Unit got offstage, 50 got ready for some promotional obligations for his forthcoming LP and film, both titled Before I Self Destruct and slated for a December 9 release. Meanwhile, outside of the dressing room, Lloyd Banks and Tony Yayo chilled with the rest of their staff and friends, talking music with MTV News Hip-Hop Editor Shaheem Reid (that would be me). The subject of mixtapes came up and Banks -- a.k.a. the PLK (Punchline King) -- said that he was amped up to drop his next one, Halloween Havoc, and wondered when Jadakiss would be dropping his street CD.

Don't miss "A Night for Vets: An MTV Concert for the BRAVE," presented by MTV's Choose or Lose campaign and CNN to support veterans of the Iraq and Afghanistan wars. The show will feature performances by 50 Cent, Ludacris, Kanye West, Hinder, Saving Abel and more and airs Friday at 8 p.m. ET on MTV.
