Lauren Bennett, the singer whose voice anchored LMFAO’s 2011 smash hit ‘Party Rock Anthem‘, has died at the age of 37. Her former bandmates in the pop group G.R.L. broke the news in a statement shared on social media. No cause of death has been disclosed.

‘Party Rock Anthem’ spent six weeks at number one on the Billboard Hot 100 and became one of the best-selling singles of that year, with Bennett’s vocals front and center throughout the track. She later went on to join G.R.L., the all-female group formed by producer Robin Antin — best known for creating the Pussycat Dolls — which released music through Kemosabe/Epic Records in the early 2010s.

The surviving members of G.R.L. — Em, Tash, and P — released the following statement:

“It is with great sadness that we share the passing of our beloved Lauren. Our hearts are broken, and we cannot begin to express how much she meant to us. We will forever cherish the love, laughter, and countless memories she gave us. Her beautiful spirit touched so many lives, and she will be deeply missed and forever loved. Rest peacefully, sweet Lauren. You will always be in our hearts. Your GRLS — Em, Tash, and P”

Bennett’s passing marks a loss for a generation of dance-pop fans. ‘Party Rock Anthem’ remains a defining cultural touchstone of the early 2010s, and her contributions to it — and to G.R.L. — left a clear mark on the era. She was only 37. We extend our most heartfelt condolences to her family and friends who survive her.
