Lily was warming up her vocal chords in preparation for a performance, and decided to do her voice exercises in nothing but her underwear.
The singer posted the snap with the caption: ‘Warming up in my pants, luckily @panosphair is there to document these dressing room moments.’
The photo was taken by her hair stylist, Papos Papandriano, and it shows Lily protecting her modesty with nothing but her laptop.
A lot of fans were impressed with Lily’s slim figure, but many blasted the star for posting such a revealing snap.
One Instagram follower commented beneath the photo: ‘If Lily Allen is going to post pictures like that, she needs to stop using Instagram, and get a Facebook. It's obscene. Kids use Instagram, and they do not want to see that!
’One of Lily’s fans stood up for the star, firing back: ‘It's always had kids on it. It's not even a vulgar picture. How is this obscene?’
When Lily posted another photo of her in a cat suit, one fan commented: ‘Thank you for putting clothes on!’
Lily has been sharing plenty of intimate moments online lately. She recently even shared a snap of herself relieving herself by the side of a road!
The star is currently promoting her comeback album 'Sheezus.'
