The 53rd Annual Grammy Awards were one for the books! While there are upsets and unpredictable wins every year at the Grammys, 2011 really outdid itself on surprises. Check out our top five picks for things we didn't see coming at music's biggest night out.

1) Esperanza Spalding Winning Best New Artist

And the winner is ... who? In a category that included the world's biggest teen heart-throb in Justin Bieber, platinum selling rap artist Drake, U.K. roots rockers Mumford & Sons and Florence & the Machine, who won Best British Album at the 2010 Brit Awards, it's safe to say no one saw jazz bassist Esperanza Spalding's win in the Best New Artist category coming. Spalding, who's latest album 'Chamber Music Society' hit No. 1 on Billboard's Contemporary Jazz Albums chart last month, is the first jazz musician to ever win the category. While her acceptance speech was sweet and showed a very humble, well-spoken young talent, Spalding even admitted she thought her win "seemed so far-fetched."

2) Eminem Not Winning Album of the Year

Eminem seventh album 'Recovery' has sold almost 6 million album across the globe, making it the second biggest album of last year, behind Lady Gaga's 'The Fame Monster.' And yet, Em failed to grab the gramophone for Album of the Year. Gaga didn't get the night's biggest accolade either, nor did Katy Perry or Lady Antebellum, who picked up Song of the Year and Record of the Year for 'Need You Now.' The winner? Indie rockers Arcade Fire. Also pumped about the win: Kanye West. "There is hope!!!" West tweeted following the Montreal band's win. "I feel like we all won when something like this happens! F---ING AWESOME!" While The BoomBox is bummed Em lost out in the category, he did win for Best Rap Album, and we couldn't agree more with 'Ye.

3) Jennifer Hudson's Banging New Body

Jennifer Hudson
started her gig as spokewoman for Weight Watchers almost a year ago. But her jaw-dropping, svelte figure during the 53rd Annual Grammy Awards tribute had everyone saying 'dayuuuuuuum!' J-Hud, who once weighed more than 200lbs and wore a size 16 has slimmed down to a size 6. With five beautiful women in a row, the former 'American Idol' contestant, dressed in a skin-tight black getup, stole the show as she belted out songs like she was Aretha Franklin during the opening tribute to the Queen of Soul.

4) No Chemistry Between Rihanna & Drake, Like, at All

Mark this performance under ... (click here for sound effect.) Sure, Rihanna looked hot. She always looks hot, but when it comes to performing 'Whats My Name?' RiRi did it better on the 'X-Factor.' Perhaps the backlash from that performance in the U.K. made RiRi play it safe at the Grammys. Not even the added bonus of her former flame Drizzy Drake onstage added any fire, making us believe that a little rumor we heard last week actually might be true, and our dream of seeing these two hookup belongs in the ...

5) Cee Lo Green's Outfit During the 'Forget You' Performance

Although Gwyneth Paltrow was a little flat on her notes, Cee Lo Green's outfit made up for it during the duo's performance of 'Forget You.' Channeling a peacock on acid and Elton John's psychedelic '70s style, Cee Lo fit in well with his back up dancers -- puppets from the off-Broadway show 'Stuffed and Unstrung.' Mr. Green won a trophy for Best Urban/Alternative Performance, but we also think he beat out Lady Gaga for best outfit at the award show this year.

Honorable Mention: Christina Aguilera's Little Tumble

After her fumble with the National Anthem at the Super Bowl XLV, The BoomBox was expecting a Christina Aguilera comeback, which she did with her singing during the opening Aretha Franklin tribute. It's what the camera's caught afterwards though, that gets her a honorable mention. As the camera zoomed out to commercial, Xtina can be seen going down in her stilettos.
