Mariah Carey and Nicki Minaj got into a heated argument last night on American Idol. During the show, Nicki pulled a cotton swab out of her purse and told Mariah she needed to clean her ears, while Mariah taunted Nicki for never having a #1 single on the Billboard Hot 100. Things spilled over to Twitter today after Perez Hilton posted that Mariah “burned” Nicki with her insults. Nicki tweeted: Bwaha! Burn? Shes said i tied her record for Hot 100 entries in only 3 years of being in the game. Yep, a black female rapper. What u SHOULD be doing (wit your messy a–) is asking why a woman SO successful at her age, is still so INSECURE, and bitter. All dem #1s but JLo phone ringin? Lol. I guess having a personality, being a secure woman, and giving genuine critique still trumps that. Lol, ok yall r so damn shady! Bye barbz!!!! Mmmuah!!!!
