Yep, that's Jersey Shore star Nicole "Snooki" Polizzi hanging out with Perry as she pulled up to the Staples Center. (Look closely, and you'll see Brand chilling in the backseat of the SUV!) Wrote Perry on her Twitter account, quoting the Black Eyed Peas lyric: "Tonights gonna be a good good night!"
The only way it could get better? If Perry won best female pop vocal performance for her hit "Hit N Cold."
