Simone Biles insisted she had "something to prove" at the Paris Olympics after inspiring the United States to victory in the women's team gymnastics event. 

Biles claimed her fifth Olympic gold medal, her first since Rio 2016, after suffering from the 'twisties' in Tokyo four years ago. 

Along with teammates Jade Carey, Jordan Chiles, Sunisa Lee, and Hezly Rivera, Team USA finished ahead of Italy and Brazil with a score of 171.296.

Team USA recorded the highest score on all four rotations and retained their crown as Olympic champions after settling for silver in Japan after Biles withdrew to protect her mental and physical health.

The Americans previously won team gold at the 2012 and 2016 Olympics and have won every team World Championship since 2011.

Biles delivered excellent performances on the bars and beam routines before a floor display that sealed the gold medal, something the 23-time world champion had set her sights on four years ago. 

"I think we all had something to prove from Tokyo 2020 Olympic Games and tonight we did just that," Biles said. 

"It means the world. This was our goal going in, even though we didn't share it with everybody because it's just a personal thing that we were working on.

"But I think for everybody it's what we came here to do. And we're super excited to walk away with that gold medal."

Biles further cemented her legacy as one of the greatest athletes of all time, moving up to the top five among gymnasts with the most Olympic golds.

She also became the most decorated American gymnast in Olympic history with eight medals, surpassing USA great Shannon Miller.

Biles has four more finals still to come, with her next opportunity coming on Thursday in the all-around final, followed by the vault final on Saturday and the floor and beam finals on Monday.
