What Olivier-nominated West-End star Marisha Wallace REALLY thinks of Louis ... trends now

West End star Marisha Wallace had one of the most iconic moments in the Celebrity Big Brother house when she was told of her Olivier Award nomination mid-task.

But her time on the show wasn't all rosy, with Louis Walsh questioning her credentials and an argument with Ekin-Su Cülcüloğlu ending in tears.

American actress Marisha, 38, is up for Best Actress in a Musical at the Olivier Awards on Sunday, for her role as Miss Adelaide in the West End production of Guys & Dolls. 

Speaking to MailOnline ahead of the prestigious awards, Marisha dished the dirt on little-known secrets from her time in the Celebrity Big Brother house and revealed what she really thinks of her all-star housemates.

Marisha was one of 13 celebrities to enter the Big Brother house on March 4 to mark the iconic series' return on ITV, alongside Sharon Osbourne, Levi Roots and Louis. 

The theatre star's Olivier nod came after Louis, 71, claimed she needed 'a few more years' before being voted for a Tony - the Broadway theatre equivalent - and insisted his former X Factor colleague Nicole was more deserving of the accolade. 

When housemate Gary Goldsmith asked whether Marisha could be nominated for a Tony this year, Louis replied: 'In time… she needs a few more years, this is Nicole's year.'

The comments hinted at a possible frosty relationship between the musical theatre star and the talent scout - but Marisha insisted that couldn't be further from the truth.

'I think I taught Louis a lot about the power of musical theatre but also the versatility of musical theatre because he asked me to sing for him all the time,' she said, revealing that the pair actually grew very close. 

'It was amazing because when he was on This Morning and he was asked who his favourite housemate was, he said me.'

Marisha said while you go into things with a 'preconceived notion of people and who they are,' she instead found Louis to be endearing.

She said: 'I think being with someone who is different than you, and seeing their struggles and what they've gone through, that it changes your whole perception and Louis is actually very vulnerable.'

And she believes she has now won the former X Factor judge round, revealing he was one of her biggest supporters in the house.

'He sent me a text yesterday saying congratulations and he said "You're a star",' Marisha explained. 'When I got nominated in the house he was cheering me on.'

During her time on Celebrity Big Brother, Marisha butted heads with Love Island star Ekin, 29.

The pair got heated when Marisha chose Ekin-Su during face to face nominations, citing that she didn't feel she could win against her. 

The reasoning infuriated the reality star and a night of tears ensued. Ekin-Su was evicted shortly after, leaving viewers wondering if there was a lingering feud.

But it seems the pair have quashed their beef once and for all, with Marisha revealing she reached out to support Ekin-Su after the show.

'We actually spoke about it when it happened and she was like "We're fine" and actually when she was evicted we were holding each other's hands,' Marisha said. 

'I don't think people realise that, that we were still tight. I told her "When I'm going to leave I'm going to defend you" because I feel like she's been through a lot. 

'She broke up with her boyfriend right before it and she was also going through a lot of things in her life. 

'To go on a show like that when you're going through a break-up? I don't know how she did it, like you would be having all kinds of feelings.'

'She's fine and yeah we're cool,' Marisha added. 'I'm cool with her.'
