Leah LaBelle mourned by Pharrell, JoJo, Fantasia & more after fatal car crash with husband Rasual Butler

Celebrities and fans alike took to Twitter on Wednesday (Jan. 31) to mourn the loss of R&B singer and American Idol alum Leah LaBelle and her husband, ex-NBA star Rasual Butler. The couple were killed early Wednesday in a single-car accident in Studio City, California.

LaBelle appeared on season 3 of Idol, alongside Jennifer Hudson and Fantasia, back in 2004 and was later signed to Epic Records, in a joint deal between Jermaine Dupri's So So Def Records and Pharrell's I Am Other label. Butler played on several NBA teams during his 13-year career, including the Los Angeles Clippers, the San Antonio Spurs and the Chicago Bulls.

LaBelle charted two songs on Billboard's charts: "Sexify," which reached No. 89 on Hot R&B/Hip-Hop Songs and No. 23 on the Adult R&B Songs airplay charts in 2012, and "Lolita," which peaked at No. 7 on Dance Club Songs.

See some of the reactions below, including from LaBelle's former label head Pharrell, onetime tourmate JoJo and fellow Idol season 3 contestant (and eventual winner) Fantasia.
