The Spice Girls singer shared the saucy snap with fans even though she had been warned not to.
Warned not to tweet this,but here goes, - hot in studio "apparently" Kate Bush took her bra off! yfrog.com/oeqghoej— Geri Halliwell (@GeriHalliwell) January 15, 2013
But the singer has also hit the headlines after being linked with gambling firm tycoon Anton Kaszubowski.
Geri and the Russian millionaire are thought to have met through mutual friends.
Speaking to The Sun, a source said, "They hit it off instantly and are seeing a lot of each other.
"Anton's just her type. He has friends in high places and loves shooting in the country.
"Geri's typically rushing into it with guns blazing, saying, 'He's the gentleman that I've been waiting for.' "
We wonder if her new man is the inspiration for her studio sessions!
