Ariana Grande Dating 'SNL' Star Pete Davidson After Mac Miller Breakup Bossip was the first to report that Grande and Pete Davidson from ‘Saturday Night Live’ have “just started” dating. Earlier this month, the ‘No Tears Left to Cry’ singer broke things off with rapper Mac Miller after dating for two years. “I respect and adore him endlessly and am grateful to have him in my life in any form.” Davidson also recently called it quits with his former girlfriend, comedian Cazzie David. It’s unclear how the pair met, but Grande appeared as a musical guest on ‘SNL’ in 2014 and later hosted with Davidson in 2016.
