It looks like Zac Efron has some steep competition for the heart of America's gold-medal-winning sweetheart Simone Biles.

In case you missed it, the cutest story of the Rio Olympics began last week after the Olympic gymnast admitted to harboring a giant crush on the hunky actor. A few days later they exchanged a series of adorable tweets, and on Tuesday Efron hopped on a plane to Brazil and surprised his famous fan in a meeting that resulted in the most heartwarming series of cheek kisses we've ever seen.

And just as we were ready to watch Efron and Biles ride off on a pommel horse into the sunset together, a third character, Brazilian gymnast Arthur Nory Mariano, vaulted onto the scene.

On Wednesday the equally hunky suitor (and confirmed platonic friend) shared a photo of him kissing Biles on the cheek, along with a caption jokingly claiming Biles's heart as his own.

"Hey @zacefron I saw her first... She is my girl," he wrote alongside the photo. "Proud of you Simone! You are phenomenal in whole world and special. You made history. Love u."
