The MTV Video Music Awards are known for being unpredictable, but there are a few things you can count on come Sunday night.

Lady Gaga will kick things off at the Barclays Center in Brooklyn by performing her new song, "Applause," which she debuted on "Good Morning America" just a few days ago.

"I'm so excited," she said of the VMAs. "We've been planning this for a year!"

Other performers include Drake, Bruno Mars, Macklemore & Ryan Lewis, Miley Cyrus ( whose number will likely include twerking), Robin Thicke, Katy Perry ( maybe she'll bring boyfriend John Mayer?) and Kanye West, who just revealed the first photo of his daughter, North. This year's Michael Jackson Video Vanguard Award honoree Justin Timberlake is slated to perform too, and as a special treat, he may be joined by his former 'NSYNC bandmates.

"You never know," Lance Bass said of the rumored reunion. "That would be an amazing, amazing time."

Among the other nominees: Jennifer Lopez, Rihanna, Kelly Clarkson and Beyoncé. Plus, Taylor Swift will be there - maybe she'll have a chance to make nice with Kanye West?

The great thing about the VMAs? Anything can happen.
