It was already shaping up to be a pretty huge night, but now, the 2009 MTV Video Music Awards have gotten even bigger. Or at least grittier and glammier.

That's because [artist id="1269"]Jay-Z[/artist] and [artist id="3061469"]Lady Gaga[/artist] have been booked to perform at the VMAs, joining an already impressive list that includes [article id="1616201"]Taylor Swift[/article], [article id="1617257"]Green Day, Pink[/article] and [article id="1616256"]Muse[/article].

Jay -- whose gnarly [article id="1613390"]"D.O.A. (Death of Auto-Tune)"[/article] is up for Best Hip-Hop Video and Best Male Video -- will perform a song from his hotly anticipated [article id="1613283"]The Blueprint 3[/article] album, due September 11. The glittery Gaga -- who, along with Beyoncé, [article id="1617536"]leads everyone with nine VMA nods[/article] -- will perform a single from her breakthrough The Fame album.

"I'm simply gutted to be both a performer and nominee at the 2009 VMAs," Gaga said. "In fact, I'm so happy, I could die."

In addition to the performers, there are some big-name presenters to add to the show too. Nelly Furtado, Miranda Cosgrove and "Gossip Girl" star Leighton Meester -- who is up for Best Pop Video and Best Direction for Cobra Starship's "Good Girls Go Bad" -- will be on hand to, well, hand out the awards. They join Katy Perry, Ne-Yo and Chace Crawford, who have already been announced as VMA presenters.

But who will they be presenting the awards to? Well, that's up to you. Voting for the 2009 MTV Video Music Awards is under way over at VMA.MTV.com. Verizon Wireless subscribers can also vote by texting VMA to 97979.
