In the raunchy vid Lily covers her chest with one arm while filming herself in the mirror.
The short clip appears to have been filmed in the ‘Sheezus’ creator’s dressing room ahead of one her concert in Hamburg, Germany.
Next to the vid, Lily has added the caption: “Cool mum #drakespanxdance”.
During her performance, she sported a number of daring costumes which all showed off her fab figure, including a skintight net jumpsuit.
She also showed off her second new hairdo of the week, sporting a bright yellow dip-dye just days after revealing an orange-streaked ‘do on Instagram.
Lily’s performance outfits are a long way from the classy, demure numbers she sported during a trip to Cannes Film Festival last week.
Since returning to the music industry in late 2013, Lily has been her usual outspoken and daring self, sparking plenty of debates online and giving a number of provocative performances, including a rendition of Beyonce’s ‘Drunk In Love’ at London nightclub G-A-Y.
