Her ex-bandmates confirmed her death in a heartbreaking statement on Monday which read, ‘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.’
A cause of death has not been publicly announced. The Daily Mail has contacted representatives for Bennett for further comment.
Bennett’s final Instagram post was shared on February 22 and showed the singer performing a cover of Nancy Sinatra’s These Boots Are Made For Walkin’.
The death comes 12 years after Bennett’s GRL bandmate Simone Battle died by suicide aged 25.
The band, created as a reboot of the Pussycat Dolls and formed by Robin Antin, was also comprised of Emmalyn Estrada, Natasha Slayton and Paula Van Oppen.
Bennett is survived by one daughter, Harlow, aged six, who she shares with dancer and Footloose actor Kenny Wormald.
The English singer first landed in the music industry in short-lived girl group, The Paradiso Girls, featuring members from different countries.
The group included Chelsea Korka from the United States, Aria Crescendo from France, Shar Mae Amor from the Philippines, and Bennett and Kelly Beckett from the United Kingdom.
They released debut single Patron Tequila featuring Lil Jon and Eve in 2009 – but later disbanded in 2010.
Her former bandmate Crescendo wrote on Instagram, ‘RIP Lauren my sister my best friend I can’t believe you left us . We spoke a week before it all happened and I could not imagine that would be the last time I would be able to talk to you.
‘Love you and miss you forever.’
Her biggest hit came in 2011 with Party Rock Anthem, which topped the Billboard Hot 100 charts for six weeks.
She later became the first member of Antin’s newest band, later known as GRL.
