Nory shared a sweet photo of him and the U.S. gymnast on Thursday, and jokingly captioned the snap with a message for Efron. "Hey @zacefron I saw her first," he quipped. "She is my girl."
The 22-year-old athlete added: "Proud of you Simone! You are phenomenal in whole world and special. You made history. Love you."
While the two look quite cozy in this pic, Biles told Us Weekly that she's just friends with Nory. "We joke that we're like international boyfriend and girlfriend because we see each other at these international meets," she explained.
They definitely have gymnastics in common. Nory was awarded a bronze medal in the men's floor exercise routine, while Biles has earned four gold medals and one bronze at this year's games. A few days ago, Nory shared a selfie of the two Olympic athletes with their medals.
"Congrats BABE! You are doing an amazing job here at the Olympics," he wrote. "The crowd and all Brazilians (including me) love YOU!"
