When you look back on 2011, you've got to admit Lady Gaga has had an incredible year. Just listen to that medley of hit songs, which Gaga performed Saturday in New York City's Times Square: "Heavy Metal Lover," "Marry the Night" and "Born This Way" all call up the past year while beating a straight path for 2012.

The singer, a native New Yorker, wore one of her signature, wacky getups — a glittery black catsuit attached to a large cage, which she tossed off midway through her performance.

Later in the night, Gaga joined Mayor Michael Bloomberg in lowering the New Year's Eve ball. This time around she wore a silver, sparkly Versace number that covered nearly her entire face.
