In the racy clip, the Smile hitmaker bared all when she posed topless for all of her 1.3million followers to see.
Lily left nothing to the imagination, wearing just a pair of blue knickers as she filmed herself in a dressing room.
The singer appeared to be in the midst of getting ready, wearing red lipstick and heavy eye make-up.
Lily's friend could be heard saying in the background: 'F***ing hell they better not be going on Instagram.'
Lily replied: 'Get banned for that, life ban.'
MailOnline has approached Lily Allen's representatives for further comment.
The star has gained a legion of followers for her candid confessions and down-to-earth attitude.
And as stars flocked to Coachella in recent weeks, Lily reminisced about her party past as she divulged she had tried 'Cali weed' for the first time at the festival back in 2007.
The Smile hitmaker looked fresh-faced in the shot while adding the caption: 'Me at Coachella 2007 20 mins before i smoked Cali weed for the first time and forgot EVERY SINGLE word of my set. Still killed it.'
Lily has made a mark on the music industry with her incredible vocal talents since she released her debut single Alright, Still which received musical award nods.
Fans will remember her first mainstream single Smile which reached number one on the UK Singles charts in 2006. No Shame is her latest album.
Lily and ex-husband Sam split in 2016 and their divorce was finalised last June.
The pair, who began dating in 2009, now have a 'very friendly' relationship and Lily insisted they are focused on co-parenting their kids.
She revealed last year they have an unconventional custody agreement, where they take their daughters for alternative weeks at a time.
Lily admitted that she cheated on her husband after struggles with fame led her to lose her identity, resulting in the breakdown of their marriage.
The singer told Vulture that she blames some of her lost self and personal troubles on her comeback to music in 2014.
She said: ‘I lost my sense of self. I lost my identity. I was being a bad mum. I was being bad at my job. I’d wake up on a tour bus in the middle of Wisconsin and be so hung-over.
'I cheated on my husband. All I wanted to do was be with my kids. I wasn’t even making any money.'
