Kanye knows how to get folks riled up. He's tweeting congrats to Brtiney for her new # 1 song and once again the gloves come off to defend himself.

Britney Spears' latest single "Hold It Against Me" has held the number one spot on iTunes since its midnight debut on Tuesday, and Kanye West made it clear that he wasn't thrilled about it, tweeting, "Yo Britney, I'm really happy for you and I'mma let you be #1, but me and Jay-Z's single ["H.A.M."] is one of the best songs of all time! LOL." LOL? Not so much.

West later removed the tweet and apologized, saying, "On a serious note I'm truly happy for Avril Lavigne and Britney Spears. No hate in 2011...I thought LOL signified a joke." Still, Spears' manager Adam Leber sarcastically quipped, "Thanks for 'letting' us be #1. Much appreciated."

As you know, this isn't the first time the unpredictable rapper has caused drama with the pop princess -- back in 2007 he reportedly had a meltdown backstage at the MTV Video Music Awards when Brit Brit replaced him as the show's opening performer.
