Tributes to American Idol singer Leah Labelle, 31

Pharrell Williams has led the tributes to “beautiful” singer Leah Labelle, who died in a car crash with EX-NBA star husband Rasual Butler.

Labelle, who was an American Idol finalist in 2004, and former basketball player Butler were killed in a single-vehicle crash in Los Angeles.

Butler, 38, and Labelle, 31, were pronounced dead at the scene after the Range Rover Butler was driving flipped over twice after hitting three parking meters and a wall.

Producer Williams, who previously worked with R&B singer Labelle when she signed to his record label, shared a collection of pictures of the two of them together on Instagram.

He wrote on Instagram: “leahlabelle, your spirit was just as your voice; beautiful. Moments like these leave us with so many questions.

“What I don’t question is how much you loved God, how much you love your life partner and where you guys are now. Sing Sis, sing.”

Singer and The Voice UK coach Jennifer Hudson, who appeared on the same series of American Idol with Labelle, said: “The world lost a shining star! My prayers and thoughts are with your family! Rest In Peace.”

Singer Jojo, who once toured with Labelle, tweeted: “Leah. beautiful sister from another mister. You will NEVER EVER be forgotten.”

Butler, who played in the NBA for 14 years, also received tributes following the fatal crash.
