Frontrunners Kendrick Lamar, Taylor Swift and The Weeknd will battle for the top honors at Monday's Grammy awards. However, British singer Adele may well steal the spotlight at the star-studded ceremony. Adele's hit album was released after the cut-off date, so she was not nominated. Swift will kick off the show with a song from her album "1989," followed by performances by Lamar, The Weeknd and Lady Gaga's tribute to David Bowie.
