Lily Allen performed a racy dance behind the scenes of NBC's Saturday Night Live before posing with fellow actress and pal Dakota Johnson.   

The Brit-award winner, 40, took to her Instagram stories reposting the sizzling clip shared by Interview magazine's editor Mel Ottenberg - capturing the singer as she did a sultry drop to the floor.

Lily looked incredible in a lacy sage green mini dress, flaunting her toned legs in glossy tights and black stiletto heels.

Elsewhere in her Stories, she was snapped cosying up to the Fifty Shades of Grey actress, 36, and SNL comedian Chloe Fineman, who originally shared the picture on her social media profile.

Dakota and Chloe looked in awe of the Smile hitmaker, gently posing their cheeks and hands on Lily, who sported a glamorous pink fur.

The snap comes after Lily got a kiss from Dakota as the Madame Web actress made a surprise cameo during the songstress' SNL performance of the track Madeline. 

Lily - who details her split from David Harbour in her new album West End Girl which dropped in October - was concluding the song when Dakota made her appearance as the infamous Madeline. 

The tune is found on her latest LP where she also references to David's affair - seemingly naming his mistress 'Madeline,' although it is believed to be a pseudonym.

At the very end of the track, Madeline offers her side of the story - which was read out by Johnson as she initially remained hidden behind curtains on the stage. 

'I hate that you're in so much pain right now. I really don't wanna be the cause of any upset. He told me that you were aware this was going on and that he had your full consent.'

The actress continued, 'If he's lying about that, then please let me know. Because I have my own feelings about dishonesty. Lies are not something that I wanna get caught up in.'

The Daddio star then added: 'You can reach out to me any time, by the way. If you need any more details or you just need to vent or anything.'

The American icon then stepped out from behind the curtains to stand directly behind Allen. 

A few audience members could be heard cheering upon recognising the actress as she placed her hands on the singer's shoulders.

'Love and light, Madeline,' Dakota said before tilting her head to lay a kiss on Allen's cheek. 

The two stars then fell into an embrace as the crowd erupted into applause following the end of the performance. 

Lily also referenced to 'Madeline' in another song on her latest album titled Tennis. 

At one point, she could be heard singing, 'So I read your texts/And now I regret it/I can't get my head 'round how you've been playing tennis

'If it was just sex/I wouldn't be jealous/You won't play with me/And who's Madeline?'

During an interview with The Times, the songstress explained that Madeline in both tracks is a 'fictional character.' 

She further explained of the lyrics: 'I don't think I could say it's all true. I have artistic license. But yes, there are definitely things I experienced within my relationship that have ended up on this album.'

Lily began dating David, 50, back in 2019 after the pair met on the dating app Raya - and they tied the knot the following year in Las Vegas. 

However, the former couple split after the songstress discovered his three-year affair and allegedly found his profile on Raya. 

'David cheated on Lily,' a source told the Daily Mail earlier this year. 'They met on a movie they did together.' 

The insider - who had witnessed the actor's interactions with his colleague - also said: 'They weren't very secretive about their relationship.'

The source added that the actor had flown the woman 'to Atlanta while he shot Stranger Things to keep him company.' 

Lily references to the end of her marriage in her album West End Girl - which dropped a few months earlier in October. 

When it came to penning the lyrics to tracks, she explained on CBS Mornings last month: 'At the time I wasn't even really thinking about it as, like, a commercial endeavor. It was an act of desperation, actually.'
