After unveiling her M·A·C lipstick earlier in the day, Nicki Minaj whipped out her Sharpie to sign copies of her debut album Pink Friday (and a few boobs) for some lucky fans at Best Buy Union Square in New York City. Hundreds of Barbz who purchased the album in advance received wristbands to meet their idol.

After the signing, she headed over to the Bowery Ballroom to perform “Monster” with Kanye West. According to HITS Daily Double, Nicki’s album is on track to debut right behind Kanye on next week’s chart.
