Simone Biles is on top of the world right now. Besides, you know, sweeping the Olympics with four gold medals like it was no big thing, she's also caught the attention of a few handsome guys. Simone's dream came true earlier this week when her longtime crush, Zac Efron, flew down to Rio to surprise her and the Final Five. In addition to making her almost faint, the actor planted a few sweet kisses on her cheek and posed for some seriously heartwarming photos. But while the talented gymnast undoubtedly fell a little more in love with Zac, there was one person in particular who wasn't as excited about their meeting. Fellow Olympian Arthur Mariano, who Simone referred to as her "Brazilian boyfriend" at the start of the Games when she posted a cuddly snap of them on Instagram, playfully called Zac out for getting too close to his favourite girl. "Hey @zacefron I saw her first... She is my girl," he wrote alongside another photo of them on Instagram. "Proud of you Simone! You are phenomal in whole world and special. You made history. Love u." Decisions, decisions . . .
