The 24-year-old "Domino" hitmaker is a huge fan of the US singer - who split from husband Russell Brand in December - and admires her strong work ethic, reported Contactmusic.
"Her hard work, her dedication, and how she deals with having the world stare at her every move, personally and professionally, with such dignity and strength, is inspiring," she said.
Born and raised in London, Jessie J released her debut album "Who You Are" in 2011 which charted at number two in the UK and has achieved success in a short span of time.
