The future of pop is here, and her name is Jessie J. staging-rapup.kinsta.cloud attended a showcase for the U.K. singer-songwriter at Stone Rose Lounge in Los Angeles this week, where U.S. tastemakers witnessed the power of the rising star. At 22 years old, Jessie has made a name for herself co-writing Miley Cyrus’ chart-topping record “Party in the U.S.A.,” and has a voice much bigger than her 5-foot-9-inch frame.

Among those singing her praises are Kelly Rowland, who was in attendance, super-producer Dr. Luke, and Justin Timberake, who called Jessie the best singer in the world right now. Not a bad endorsement.

The petite Brit blew away the industry crowd with material from her Lava Records/Universal Republic debut Who You Are, including the reggae-tinged “Stand Up,” feisty “Mamma Knows Best,” B.o.B-assisted “Price Tag,” and first U.S. single “Who You Are.” She also won over new fans with her first live performance of “L.O.V.E.,” rumored to have been written for Alicia Keys. Watch below and find out why we’re in L.O.V.E. with Jessie.
