Who are Simone Biles biological parents? Everything to know about the Olympic star's adoptive family life with

As Simone Biles gears up for her Olympics return in Paris, the decorated American gymnast will have the undying support of her parents.

After her run at the Tokyo Games ended in a withdrawal, the 27-year-old hopes to make a comeback and add to her four Olympic gold medals as she spearheads Team USA.

With an already legendary career in her field, Biles often raves about her upbringing and her relationship with her parents.

Simone and her siblings were adopted by their grandparents, Nellie and Ronald Biles, when she was six. Since then, she has called them Mom and Dad.

In the Facebook Watch series 'Simone vs. Herself,' Biles revealed that her biological mother, Shannon, struggled with drug and alcohol addiction. As a result, she and her three siblings were placed in foster care when she was three.

Biles' biological parents both suffered with drug and alcohol addiction 

Biles recalled her biological mother being in and out of jail and how they sometimes went without food.

'I don't remember a lot about foster care, but I definitely knew that we had been taken from our biological mom, and then you just think you're going to go back to her,' Biles shared.

Biles' biological father, Kelvin Clemons, met Shannon while they both were teenagers and also struggled with addiction. In a 2016 interview with the Daily Mail, Shannon revealed she occasionally speaks with Kelvin-- who is not in touch with their daughter. 

'He just called me Sunday. I said, 'I'm watching Simone are you watching her? Are you watching her? Call me back later,'' she recalled then. 'He knows that's his daughter and he's very proud of her.' 

Simone's maternal grandparents, Nellie and Ronald Biles, adopted her and her siblings

Nellie completely supported her daughter's decision to withdraw from the Tokyo Olympics 

Biles also shared how 'fortunate' she was to stay with her siblings instead of being split into different homes. She also expressed her gratitude towards her grandparents for their love and support.

'Being separated from my biological mom, being placed in foster care before I officially got adopted by my grandparents, it just set me up for a better route at life,' Biles said. 'I feel like I wouldn't be where I am unless that turning point happened.'

Nellie Biles, Simone's grandmother, cherished the moments she shared with Biles and her siblings, claiming: 'I remember praying for that bonding.'

Because telling them that you love them and you care for them; that's all words,' Nellie continued. 'But then you wake up one day, and you realize that you would do anything for these children. And that you would die for these children. And when that feeling comes, that's when you know you are truly a mother.'

The bond proved strong as Biles leaned on her mom at her lowest points, including her breakdown at the Tokyo games.

Their relationship shined in the Netflix docuseries 'Simon Biles Rising' when Nellie's reaction to Biles withdrawing was seen by the public.

'You can't do it. It's okay, honey,' Nellie said after receiving a call from her daughter. 'They will do their best without you.'

With her return to the world stage, Biles and her teammates were surprisingly absent from the star-studded opening ceremony and parade of nations. As fans wondered about her absence, Nellie was first to explain why her daughter skipped the festivities.

'The first competition is Sunday,' Nellie explained, 'which is the Women's Qualifier. And, of course, she needs to rest up before that competition.'
