Coco Gauff was "One Less Lonely Girl" Friday at Arthur Ashe Stadium as she booked herself a spot in the U.S. Open fourth round in front of Justin Bieber.
The 19-year-old American said she was "fangirling" when she found out Bieber and his wife, Hailey Bieber, were in the stands cheering the teenager on.
"I was definitely starstruck with Justin Bieber [in the stands]," Gauff said after her win against Elise Mertens. " Then Hailey [Bieber], too, coming. I guess it was a little date night for them, which was really cool."
Gauff turned her third-round match around after dropping the first set to win the battle 6-3, 3-6, 6-0.
"'Never Say Never' was like the first, I think one of my favorite songs when I was a kid. Then 'Baby, Oh, Baby,'" Gauff said about her favorite Bieber songs. "I could go through all his songs."
The teenage sensation has already had a long list of notable people watch her play at the U.S. Open -- from athletes all the way to politicians Michelle and Barack Obama.

But who is at the top of her list for celebrity appearances? The one and only, Beyonce.
"I guess which celebrity I would be starstruck, definitely Beyonce," Gauff admitted. "If she ever came, oh, my goodness, I hope they would not show her on the screen. Maybe at the end."
Gauff will face Caroline Wozniacki in the fourth round of the U.S. Open on Sunday.
