Scarlett Johansson stuns in a thigh-skimming white dress, delivering a provocative dance as she hosts SNL.

In a sixties-inspired thigh-skimming shift dress, Scarlett Johansson gave viewers of SNL something to set their pulses racing – a very sexy dance.

The 30-year-old Avengers star kicked off hosting the Saturday night show by announcing, ‘I’m officially a MILF’ and then proving that is definitely the case.

The star clarified that she meant, ‘Mother In Lots of Films’ rather than the more commonly used x-rated acronym.

Scarlett gave birth to her daughter Rose last September and proudly told viewers she’s the ‘best thing to happen to me’ before starting a sketch where she sings Donna Summer’s Love to Love You Baby in an exaggerated sexy fashion to her daughter as a lullaby.

The star – who is married to Rose’s father Romain Dauriac – treated viewers to a playful dance where she rubbed her hands all over her body which would probably count her as the sexiest MILF on the planet.

She showed off her perfectly toned legs in the simple dress which emphasised her curves and red high heels.

The actress flung her hair around and even licked her finger provocatively into the camera lens.

After kissing her finger and putting it on her behind, she asked: ‘It’s cute, right?’

The joke culminated with the star of Lucy being joined by four sexily clad dancers – introducing them as the ‘gals from my mommy and me group’, to gyrate to her baby’s lullabies.

She then revealed what her baby daughter looks like.

‘People say she looks just like me’, the star said before showing a creepy collage of her own head on a baby’s body.

Wiz Khalifa joined Scarlett as the musical guest on the legendary show which celebrated 40 years on air last month.

ScarJo has been doing the late night TV show rounds as she promotes the Avengers sequel, Age Of Ultron.

Her main skit as host of the famed late night comedy show saw her revive her role as Black Widow – and making a clear dig at the sexism in her blockbuster Avengers movies.

After admitting that the films always center on male heroes, she then joked about how Hollywood would make a female superhero movie into a cliched romantic comedy.

‘Does Marvel not know how to make a girl superhero movie?’ a voice over said at the start of the skit, with the words written up large on the screen.

‘Chill – Marvel gets women,’ the announcer added, leading to scenes of Scarlett running across the road and snapping her heel, Sex And The City style – before landing a job at Fashion Weekly, just like from The Devil Wears Prada.

‘The only thing missing in Black Widows life was love,’ the announcer added – as Black Widow stumbled across Ultron while walking in the park, her shyly shaking his hand as he asks her for coffee.

‘I don’t really have any time to date guys now,’ Black Widow said, blushing as Ultron replied: ‘What about robots?’

A clearly gay Thor acts as her best friend asking: ‘So, who’s the guy?’

‘From Marvel studios… an the writers of 27 Dresses comes the story of a super hero and her super romance’ the announcement continued, as Black Widow and Ultron become close despite her fellow heroes warning her she is ‘moving way too fast’.

In one scene, Ultron unzipped his pants, leading to flashing nights and mechanical sounds before he stated proudly: ‘Penis activated.’

But Black Widow was soon left in tears as Ultron flashed up on the news on TV – having thrown a bus at her office building.

She kicked him to the curb when he tries to apologize – then ended the skit seemingly falling for The Hulk, who won her over by knowing her favorite food was ice cream.

‘For Black Widow, falling in love can be hard, but it can also be Incredible,’ the voice over announced, before adding: ‘Marvel. We know Girls.’

Scarlett is getting set to play the lead role in a film adaptation of the Ghost in the Shell franchise later this year.
