Doubt (Mary J. Blige song)

"Doubt" is a song by American recording artist Mary J. Blige. It was written by Blige along with English musician Sam Romans for her thirteenth studio album The London Sessions (2014), while production was helmed by Romans and American record producer Rodney "Darkchild" Jerkins. Released as the album's fourth single, the ballad has since reached the top ten on Billboard's Adult R&B Songs chart.
