If you wanted to know who the biggest fan of the US Open was this year, we'd like to point your attention towards Justin Timberlake.
On Saturday night, the singer and his wife Jessica Biel watched tennis star Roger Federer beat Spain's Feliciano Lopezi in the third round of the men's singles tournament at the 2017 U.S. Open at Arthur Ashe Stadium.
However, we were far more excited by the former N-Sync band members facial expressions than the match, as it appears Timberlake well and truly lost his sh*t during the game.
Justin was spotted looking in shock, awe, happiness and relief during the match, much to his amused mother of his child.
The pair were also spotted enjoying each other's company, laughing at jokes and kissing during the match.
The 'Rock Your Body' crooner has attended the annual tennis championship every other year since 2009, according to E! News, along with his wife of five years.
At the 2015 U.S. Open, Timberlake and BFF comedian Jimmy Fallon even treated fans to a dance in the stands to Beyoncé's hit single 'Single Ladies'.
Justin is loving life right now, clearly.
