The millionaire co-founder of CrossFit is planning to marry a man who is currently sitting in a Florida jail on murder charges - and she won't even make him sign a prenup.

Lauren Jenai, 47, is looking forward to a jail wedding with Franklin Tyrone Tucker, a childhood friend from Philadelphia who she reconnected with on Facebook following her divorce from CrossFit co-founder Greg Glassman in 2013.

Tucker, 47, has been in prison since 2017 after he was arrested for allegedly stabbing a man to death during a robbery.

Tucker was charged with first-degree murder alongside Rory Hank Wilson and John Travis Johnson in the death of Mathew Bonnett.

Bonnett, 59, was killed in November 2017 after he heard a commotion while his neighbor was being robbed at knifepoint.

Prosecutors claim that Tucker and Wilson stabbed Bonnett multiple times as they were leaving the scene. Police believe Johnson was the getaway driver.

All three men were also charged with armed robbery. Tucker also faces a witness tampering charge after he allegedly threatened a witness five days after the murder, according to the Miami Herald.

Jenai has risen to Tucker's defense since his arrest, hiring a private investigator and a New York lawyer to help his case. The multi-millionaire also told the judge she was willing to post Tucker's $1million bail.

The mother-of-four, who currently lives in Portland, said she believes Tucker is innocent and was simply an 'easy target' for police.

While the pair had begun chatting on Facebook years before Tucker's arrest, it was the murder case that turned their connection into a romantic one.

The pair began video visitation - as Tucker's prison no longer allows in-person inmate visits - and the sparks quickly flew.

'We hadn't seen each other in 30 years. We turned into little high school kids together,' Jenai told Page Six.

'We started having feelings for each other through the process and developed a really special relationship. Now the plan is when he bonds out, he's going to live with me in Portland. We're going to get married. We're engaged.'

Plans have changed since Tucker's bail was denied during a January 29 hearing, a decision that Jenai said left her 'devastated'.

But the fitness guru is now planning to wed Tucker in jail. It will be the first time they get to be together in the same room since their romance began.

'Even though this is a relationship that's not physical, he and I have known each other for such a long time,' she said. 'It doesn't seem strange to me that we have feelings for each other. It's been a year of constant communication.'

And Jenai said she won't have Tucker sign a prenup because it feels 'a little inappropriate'.

'Our relationship is very open and we are a team,' she said. 'I trust him. I love him. My house is his house.'

And that house is a big one. Jenai sold her CrossFit shares for $20million during her messy divorce with Glassman, which stretched from 2009 to 2013 before it was finalized.

Now the founder of new fitness program Manifest, Jenai is intent on being reunited with her high school crush.

The separation has no doubt become even tougher for the couple after they were banned from video visitation.

'I got a little risque,' Jenai admitted. 'I was touching my boobs. I got a warning. I stopped.'

Jenai's account was suspended for three years, so she began video visitation with Tucker using her mother's account. But it happened again.

'The heat of the moment sometimes gets the best of you,' she said. 'I want to be a good fiancée to him. My boobs popped out at some point, it happens.'

Jenai later learned her mother's video visitation account had been suspended for 100 years. Tucker was also ordered to go into solitary confinement.

She believes authorities are trying to keep her away from Tucker to try and 'break him down'.

'I keep him sane,' she said. 'They get you in jail and they leave you there, and you get so frustrated that you make deals and plea to things you haven't done.'

'They're trying to break him down and scare me away.'

But Jenai said she is standing by Tucker's side and has the support of most people in her life.

'People who know Ty, like my mom, she knows the whole situation and she's very supportive,' she said.

'People who don't know him - who don't see my relationship with him - I can tell they think it's a bad idea and they think I'm crazy. Especially my ex-husband.'

'I just know this whole situation is wrong,' she added. 'And I have a story to tell.'
