Tennis star Coco Gauff has mourned the loss of TikTok’s app back home. The 20-year-old from Florida wrote “RIP TikTok USA” on a TV camera lens and drew a broken heart right after winning a match at the Australian Open to reach the quarterfinals.

With a 6-1, 6-2 victory over 14th-seeded Mirra Andreeva to open play Sunday at Rod Laver Arena, Aryna Sabalenka advanced to the quarterfinals of the Australian Open. She'll be joined there by Coco Gauff.

While most American tennis fans were asleep late last night, Gauff defeated Leylah Fernandez in straight sets of their third-round match at the Australian Open: 6-4, 6-2. In her post-match interview, Gauff reminded everyone why she is so relatable, even if it was embarrassing.
