Lady Gaga to sing at Super Bowl, Grammys

Lady Gaga will perform at two of February's most-watched events as she sings the national anthem at the Super Bowl and leads a tribute to David Bowie at the Grammys.

The National Football League announced that Lady Gaga would sing The Star-Spangled Banner at Super Bowl 50 on Sunday in San Francisco, where British rockers Coldplay will be the halftime entertainment.

The Super Bowl is often the most-watched television event each year in the United States, and the league generally seeks out noncontroversial performers.
