The 28-year-old sang Hard Out Here for the first time 400ft in the air – during a special gig which took place in one of the pods of the London Eye.

She joined Mark Ronson and her ex-boyfriend, DJ Seb Chew in the YoYos pod at a special Red Bull event on the famous London landmark. The pod was named after the Notting Hill club where Lily performed before hitting the big time.
The Revolutions In Sound event saw 30 of the London Eye pods being taken over by iconic London clubs hosting their own parties to celebrate the 15th anniversary of the Red Bull Music Academy.
DJs taking part included Richie Hawtin, Gilles Peterson, Mr C, and Sasha - and the music was streamed online and to 2,000 clubgoers attending a Silent Disco on the Thames embankment below.
Lily glammed up for the event in a snakeskin-print dress featuring prints of cartoon snails. She kept warm in a fur coat and was rocking the same long ponytail she had in her Hard Out Here music video.

Lily hits out at gender inequality in her new track, which has already caused controversy with its explicit, expletive-laden lyrics, and provocative video.
It begins with Lily lying on an operating table undergoing liposuction. A record company executive, possibly her manager, asks: "How does somebody let themselves get like this?" to which she replies: "Erm, I had two babies".
The video then launches into a parody of hip hop videos in general, with references to Robin Thicke's Blurred Lines and much twerking, à la Miley Cyrus at the MTV awards.
"You'll find me in the studio, not in the kitchen," sings Lily by way of an introduction, before firing off a series of gender injustices and stating in the chorus that "it's hard out here" for females of the species in the music industry, and the world in general.
