Gigwise has it on good authority that Florence & The Machine are booked to play Glastonbury Festival this June.
Florence Welch and her band will perform at a prominent time slot on The Other Stage, possibly on the Saturday, we're told.
In keeping with her chart-topping, Brit Award winning success, it will be a big step up for Florence after playing the John Peel Stage in 2009.
The news comes less than a day after Florence & The Machine were confirmed as one of the three headline acts at Latitude alongside Vampire Weekend and Belle & Sebastian.
Glastonbury Festival 2010 is headlined by U2, Muse and Stevie Wonder, while Jack Johnson and Corinne Bailey-Rae have previously been confirmed for slots on the Pyramid Stage.
Other names rumoured for the 40th anniversary event include Hot Chip, Andy Williams and, erm, The Wombles.
Glastonbury takes place at Worthy Farm, Pilton from June 23rd to the 27th 2010. All tickets are completely sold out.
