Smiling Rebel Wilson leaves a gym in Hollywood days after Sacha Baron Cohen and Isla Fisher's divorce  was revealed - after saying her memoir had nothing to do with the couple's split

Rebel Wilson stepped out for a stroll this week amid the fallout from her tell-all memoir.

In the book, the 44-year-old accused former co-star Sacha Baron Cohen of inappropriate on-set behavior - just days before the Borat actor announced his separation from wife Isla Fisher. He has denied all the allegations.

On Thursday, Rebel tried to keep a low profile as she left a local gym in West Hollywood.

She was styled perfectly for a workout in a white tank top, black leggings and trainers, with a gym bag slung over one shoulder.

The Australian actress tied her blonde her back into a messy ponytail and donned a pair of aviator sunglasses.

It comes after Sacha, 52 and Isla, 48, announced they had quietly separated last year by sharing a bizarre snap posing in tennis outfits.

It has since been claimed that Rebel's allegations against Sacha - which he has strenuously denied - were the catalyst for his marital break-up.

Rebel has denied being the reason for Baron Cohen and Fisher's divorce.

'I don't think I had anything to do with their divorce. His actions were with multiple people,' she told an audience while promoting her memoir.

'From what I was told they started the process over the past year. I think some of the headlines put pressure on him to announce it.'

She continued: 'But I think Isla is an amazing person and the sad part of all that is I was friendly with her, not good friends but friendly, and the sad part of all that is after it all happened on Grimsby I didn't talk to her ever again.'

Wilson concluded that she wishes the Confessions of a Shopaholic star, 48, 'well' and hopes 'it's going to be all right' for her.

But, ultimately, she 'really' does not think their split has 'anything to do with' her.

In her memoir, Rebel described her experience filming the 2016 movie The Brothers Grimsby with Sasha Baron Cohen, whom she has referred to as an 'a**hole'

Speaking on Andy Cohen on Watch What Happens Live, Rebel insisted that she would never work with Sacha again.

'No money ever. Yeah. I have a no a-holes policy with work,' Rebel insisted, as many in the audience applauded.

When Andy started throwing dollar amounts such as $20 million, $30 million and $50 million, though Wilson insisted she still would not work with him.

Since news of Sacha's split, Rebel warned in an interview on Saturday that 'the truth will come out'.

Representatives for Sacha say he denies any allegations of mistreatment or harassment towards Rebel on the set of 2016 action comedy flick Grimsby, released in North America as The Brothers Grimsby.

Rebel says other women have 'been in contact' with her since she made the claims in her new autobiography, Rebel Rising. There is no suggestion at this time that the women are making claims against the Borat actor.

She continued: 'It is hard to say something against somebody who's high profile, because they hit you with high-price lawyers and crisis PR people and all sorts of little tricks.

'It doesn't feel great when all I'm doing is sharing my story in my memoir, which I'm very entitled to do.

'But I always think that the truth will come out which is why it's great to have the book out now so people don't just read the headlines, but can read the actual chapter.'

It comes after Sacha, 52 and Isla, 48, announced they had quietly separated last year 

The remarks, first reported by The Sun, come after days of frenetic speculation over Baron Cohen's marriage after Rebel's book was released.

She had played Baron Cohen's on-screen girlfriend in Grimsby, a box office flop that was derided by critics.

The film saw Baron Cohen's football fan character Nobby get drawn into the world of espionage; it also starred Isla, Mark Strong, Penelope Cruz, Ricky Tomlinson and Johnny Vegas.

Rebel claimed in the memoir that during filming he would ask her to strip off for scenes, in violation of her 'no nudity' clause, and requested that she perform a sex act involving his bottom on camera because it would be 'funny'. Her claims have been dismissed as 'demonstrably false'.

She wrote that his actions made her feel 'completely disrespected, which led to me treating myself with even more disrespect by eating in an extremely unhealthy way'.

Bridesmaid actress Rebel said she eventually compromised and agreed to 'slap him on the a**' in an improvised scene, and agreed to it after several rewrites.

But behind-the-scenes footage released after the claims were made appeared to suggest she was on board with the scene - a suggestion she has vehemently denied.

'It is an a****** move to release footage of one part of that disgusting episode while leaving out everything that preceded it,' she said in a statement, adding that her 'horrified refusal' to carry out the act was not included in the released footage.

She added: 'What this edited video shows is what I had to do in order to get out of the room, as written in Rebel Rising.

'Releasing unauthorized and misleading behind the scenes video without my approval is SBC's (Sacha Baron Cohen's) latest way of bullying and gaslighting me.'
