His marriage to wife Jada Pinkett Smith is said to be on the rocks.

And new pictures showing Will Smith cavorting with his lingerie-clad co-star will only add fuel to the fire.

The 45-year-old is seen cosying up to his Focus leading lady Margot Robbie, 23, in leaked photos taken in a photo booth at a New Orleans party in October.

Reps for Will and Margot did not respond to MailOnline’s request for comment.

In the pictures, released by Star magazine, the Australian actress lifts up her top to reveal her lacy white bra, as Will does the same behind her, pressing his bare chest against her back.

She looks up at the actor and suggestively pouts her lips.

In another shot, he pulls her towards him from behind, their face pressed close together side-by-side.

‘He wasn’t acting like a married man; he gave no signs that he was in a committed relationship,’ an eyewitness told the publication.

‘What kind of married man would go into a photo booth with a sexy 23-year-old girl and start to undress?’

Jada wasn’t present at the October 25 party, and was instead speaking at a charity event in Baltimore.

‘When we did our audition together, we had a natural chemistry,’ Margot previously said of her costar. ‘I think it’s going to be a lot of fun.’

The flirty new pictures were taken at a crew party after shooting had wrapped for the day.

An eyewitness told Star that Margot asked Will to step into the photo booth with her.

‘Once they pulled the curtain back to take the pictures, they let their inhibitions run wild, laughing, hugging and nuzzling each other in the dark,’ the insider said.

‘Margot directed Will before each pose. First the ordered him to act like a gangster. Then she covered her face with a masquerade mask and leaned into his chest. Next, she asked Will to take a sexy picture with her, as she pulled up her shirt and exposed her lingerie for Will and the camera.

‘They were hanging all over each other, laughing like they were a new couple in love,’ the source continued. ‘Will had just gotten done working for the day, so he definitely wasn’t intoxicated in any way — he knew what he was doing.’

Sending a message? Jada was seen without her wedding ring on Monday at a charity event in LA

After the photo session, Will allegedly hoisted Margot on his back ‘piggyback style’.

‘They didn’t seem to care if anyone saw them do this. Then they took off, giggling, with her riding on his back, holding him tight with her head resting on his neck and back as they headed toward the trailer.’

The duo didn’t wait for their photos to be printed, although Will’s assistant apparently confiscated them, reports the magazine.

‘Will and Margot never showed up back on set or attended the night’s festivities with the rest of the crew,’ the insider revealed.

‘After they left the party, they were gone all night.’

Meanwhile, Will and Jada haven’t been photographed together since they were in New York City with their children on August 23.

And Jada has issued a few odd statements lately.

On October 23, she told the audience at the Associated Black Charities of Baltimore Girls’ Night Out Event, ‘When you are going through a storm with your spouse… stop thinking about what you “believe” a husband or wife should be.’

‘I thought success would make me happy … It does not,’ Jada also reportedly said.

She also stepped out without her wedding ring on Monday night.

And last month, the Smiths listed their $42 million Southern California residence after unloading their Hawaiian spread.
