Beyoncé started the decade with a historic night at 2010 Grammys. The singer, who had released I Am . . . Sasha Fierce, won the most awards by a female artist in one night (the record was later tied by Adele in 2012). That night, Bey won best female R&B vocal performance, best R&B song, and song of the year for "Single Ladies"; best female pop vocal performance for "Halo"; best traditional R&B vocal performance for "At Last"; and best contemporary R&B album for I Am...Sasha Fierce.
That year, Bey also released the now-iconic "Telephone" music video alongside Lady Gaga (who was also on her way to mega-fame) and dropped her documentary, I Am...World Tour, which gave fans a closer look at her 108-show tour that spanned from March 2009 to February 2010.
