English singer/songwriter Jessie J combines deep, soulful vocals, a sharp pop sense, and a down-to-earth manner that recalls Beyoncé, Gwen Stefani, and P!nk. Overcoming various career setbacks and health issues, she issued a trio of U.K. Top Five albums -- Who You Are (2011), Alive (2013), and Sweet Talker (2014) -- in the early 2010s, while also recording multi-platinum, chart-topping singles "Price Tag," "Domino," and the superstar collaboration "Bang Bang." Though things cooled down as the decade drew to a close, she continued to release music, including 2018's R.O.S.E., while branching out into television singing competitions, both as a contestant (winning China's I Am a Singer) and a judge (on The Voice Kids UK).

Born Jessica Cornish in Chadwell Heath, London in 1988, she started her career in showbiz at the age of 11, performing in the West End production of Andrew Lloyd Webber's Whistle Down the Wind. After studying musical theater at the prestigious BRITS School, she signed a deal with indie label Gut Records, which went bankrupt before releasing any of her music.

Following a minor stroke at age 18, she gained a Sony publishing contract and penned hits for the likes of Chris Brown, Dutch X Factor winner Lisa Lois, and Miley Cyrus (the American number two hit "Party in the USA"). After building an established online presence, she signed to Universal Records and began working with the likes of hitmaker Dr. Luke (Katy Perry, Kelly Clarkson), Atlanta rapper B.o.B, and R&B producer Labrinth on her debut album, Who You Are. In 2010, her first single, "Do It Like a Dude," originally written for Rihanna, reached number 25 on the U.K. charts and, following in the footsteps of Adele, Florence + the Machine, and Ellie Goulding, she won the Critics Choice Award at the 2011 Brits. That same year, an appearance on Saturday Night Live coincided with her album being reissued in the U.S.

Following a tour that took her to the U.K., Ireland, Australia, Malaysia, and her first stop in North America, Jessie J became the first U.K. female solo artist to achieve six Top Ten singles from a single studio album. The success of the sixth single, "LaserLight," featuring David Guetta, was aided in no small part by her appearance as a judge on the U.K. edition of The Voice. The hit show gave the singer a chance to display her talent for musical coaching, while building a rapport with fans both old and new on prime-time television. Also involved were Tom Jones and will.i.am, with whom Jessie J performed at Queen Elizabeth II's Diamond Jubilee Concert in June 2012, before heading back to the studio to work on the follow-up to Who You Are.

After finishing her second and final season of coaching on The Voice in 2013, J returned with the singles "Wild" and "It's My Party," which preceded her second album, Alive, that September. With a planned U.S.-only version of Alive featuring collaborations with Pharrell Williams eventually put aside, J instead focused on recording new material for what would become her third studio LP, Sweet Talker. Including the likes of Diplo, the-Dream, and the aforementioned Pharrell, the album also saw her join forces with De La Soul and 2 Chainz, while Ariana Grande and Nicki Minaj both featured on the lead single, "Bang Bang," which debuted at number one in the U.K. and became a Top Ten hit in the U.S., Canada, Australia, New Zealand, and Bulgaria. Sweet Talker arrived in October 2014, reaching the Top Ten in the U.S. and U.K. Taking a break from music, she joined the cast of judges on the 2015 season of the television singing competition The Voice Australia. That year, she also embarked on a tour in support of Sweet Talker.

Jessie J issued a handful of new singles in 2017, including "Real Deal" and "Queen," which were slated to appear on a planned 2018 LP. Before that, however, she dipped back into television singing competitions, only this time, she was a contestant. China's I Am a Singer 2018 featured J as the only contestant not based in Asia, competing against Taiwan pop diva Angela Chang, X Factor Philippines winner KZ, and a host of others from China, Taiwan, and Hong Kong. J took the crown that April, becoming the first non-Chinese singer to win it all. Returning to her music, she issued the four-part R.O.S.E. album, which arrived in EP-sized chunks over the course of four days in May 2018. Split into R (Realisations), O (Obsessions), S (Sex), and E (Empowerment), the set was produced by DJ Camper. She capped off her busy 2018 with the release of the holiday album This Christmas Day.

The following year, J extended her onscreen time as a judge on the third season of the U.K.'s The Voice Kids singing competition. Though things remained relatively quiet on the musical front, she closed the decade with a handful of single releases, including a collaboration with Don Diablo, "Brave." In 2020, she teamed with pop singer Mike Posner for "Weaponry" from his album Operation: Wake Up. She returned to the fore in 2021 with her disco-blasted single "I Want Love." ~ Jon O'Brien & Daniel Clancy, Rovi
