Last night, diva Mariah Carey sang her ass into the New Year by performing at Madison Square Garden in NYC. Word is MiMi put on a great show and it was very entertaining–unlike the usual boring and almost always identical performance she puts on. She sang a few of her classic hits and some new tunes including Obsessed and H.A.T.E.U., while hubby Nick was on the 1’s & 2’s.

Meanwhile, The Black Eyed Peas rang in the New Year on the West Coast playing hosts at LAX Nightclub in Las Vegas.

Hip-hop pioneer LL Cool J is set to host “The Grammy Nominations Concert Live: Countdown to Music’s Biggest Night”, a one-hour special which will take place at Club Nokia in Los Angeles. Looks like bosses over at the Grammy Awards are definitely taking heed to the good ole’ saying “if ain’t broke, don’t fix it” ’cause tomorrow night will mark the second annual live primetime nominations for the Grammy Awards. Last year’s airing did so well that bosses over at the Grammy Awards decided to take a shot at it again this year! This year’s presenters include Linkin Park, George Lopez, T-Pain, Smokey Robinson, Katy Perry and a bunch of other celebs. “Sexy B*tch” hitmaker David Guetta is set to spin tunes throughout the special, which also features performances by Black Eyed Peas, Maxwell and much more.  “The Countdown to Music’s Biggest Night” begins tomorrow night, Wednesday, December 2^nd on CBS at 9 p.m.

The clock stops ticking on January 31, 2010, as the 52^nd annual Grammy Awards will take place at the Staples Center in L.A. and will air live on CBS at 8 pm.
