(USA Today)-- Beyonce's just full of surprises lately. Not only did she make history with her stealth album release, but she'll also perform at the 56th Grammy Awards (CBS, Sunday, 8 p.m. ET/tape delay PT). And she's not even a nominee.
Although music's most important night should belong to the nominees and winners, Queen Bey's metaphorical crown could overshadow all the hopefuls, as well as the other performers. As surprising as it is that Beyonce will perform when she isn't in the running, she joins a long tradition of Grammy performers who had nothing to do with that year's nominations. Here's a look back at a few:
Earning seven Grammy nominations may not seem like a reason to cry himself a river, but JT was shut out of the marquee categories, most notably album of the year, despite The 20/20 Experience being the biggest-selling release of 2013 (2.43 million copies). Nomination-free at last year's Grammy Awards show, he nonetheless smoked the stage in his Suit & Tie with assists from Jay Z and full string and horn sections.
Also at the 2013 show, Mars shared the stage with Sting for a tribute to Bob Marley, entwining Locked Out of Heaven and The Police's Walking on the Moon before Rihanna and Damian and Ziggy Marley joined them for rousing rendition of Could You Be Loved. Though Mars' Locked Out of Heaven was on the charts at the time, it wasn't eligible for a Grammy nomination until this go-around.
In music, 2012 will forever be remembered as the year we lost Whitney Houston. Her death, just hours before she was to attend Clive Davis' star-studded pre-Grammy Gala, left the world reeling. In homage to the loss of "the Voice," Jennifer Hudson stepped up with a powerful rendition of I Will Always Love You.

Celebrities scrambled to help after Haiti was decimated by an earthquake in 2010, with Bocelli and Blige making a split-second decision to duet at the Grammys, singing Simon & Garfunkel's Bridge Over Troubled Waters. All proceeds from sales of the single on iTunes went toward earthquake relief.
As the years stretched on after the band's 1984 breakup, hopes of a reunion became bleaker. But at the 2007 Grammy show, the guys gathered onstage to play Roxanneand make those rumors official. "Ladies and gentlemen, we are The Police, and we're back!" Sting confirmed. They then went on rake in $300 million on a world tour.
