Tom Cruise, Lady Gaga, John Legend, Ariana Grande and Vogue editor-in-chief Anna Wintour were among the celebrities packed into Bercy Arena on Sunday to witness the return of Simone Biles to the Olympic gymnastics stage for the qualifying round.
Biles, the most decorated gymnast in history, is back for her third Games after withdrawing from most of her events at the Tokyo Games in 2021 with mental health issues.
She leads a veteran squad seeking redemption after the US team finished second in Tokyo -- thus ending their hopes of completing a hat-trick of Olympic team titles following their success in 2012 and 2016.
"It's awesome," Cruise told Reuters in the stands at the Arena.
"Great stories, great athletes. It's incredible what they do."
Singer John Legend and wife Chrissy Teigen said there was nowhere they would rather be.
"This was on our bucket list. We wanted to make sure we came to this event," he told Reuters.
"They represent the best of America and we are so proud and excited for them. Let's go USA."
The sold-out arena erupted when the US team was announced and let out a deafening roar when four-time Olympic gold medallist Biles was introduced.
Biles abruptly pulled out from the team final at the Tokyo Games after suffering from the "twisties", a term used to describe the temporary loss of spatial awareness while performing high-difficulty elements.
On Sunday she powered the runaway favourites for the team title to the top of the qualifying standings. The top eight qualifiers will contest Tuesday's final.
"She is so resilient," said NFL great Larry Fitzgerald.
"To be able to overcome that and put herself back in position to be able to do something is truly remarkable."
A five-year-old Biles super fan named Georgia, who was in the stands with her father Andrew Pearce of Alabama, said she planned to follow in her idol's footsteps as she performed some impressive gymnastics manoeuvres in a corridor outside the competition arena.
"I'm practicing because when I grow up, I'm going to be in the Olympics," she said.
