2011 was a big year for pop star Lady Gaga. When her album "Born This Way" was released in May, 1.1 million copies sold in the first week. It outsold the next 42 albums on the Billboard chart combined. As of October, worldwide sales had surpassed 8 million copies. And she continues to release ambitious videos - most recently the 13-minute epic "Marry the Night," which grabbed 5 million views in less than 48 hours.
Lady Gaga was a regular presence at award shows throughout the year. She won three Grammys in February, including best female pop vocal performance. She won two MTV Video Music Awards in August. And she was recently nominated for three Grammys for next year, including best album.
