Coco Gauff is ready to make Olympic history at the 2024 opening ceremony in Paris, but the 20-year-old tennis star says there’s one main thing she’s concerned about ahead of the event.

Gauff, 20, tells PEOPLE during a press conference in Paris that she’s mostly “not nervous” about her gig as flagbearer alongside LeBron James during the Parade of Nations, where she’ll be the first U.S. tennis player and youngest American flagbearer in Olympic history.

“I don’t know, I feel like you just hold the flag so I don’t think I can mess it up too much,” Gauff says.

But, “I am a little concerned about the height difference,” the 5-foot-9 athlete says of the 6-foot-9 NBA star.

“Is my arm going to be up here while he’s holding it? I don’t know. I thought it was two separate flags when I was looking at a picture. They hold it together, so I don’t really know,” Gauff adds.

As for competing, Gauff admits to “a little bit” of nerves ahead of her first Olympic match against Ajla Tomljanović. “Obviously it’s my first Olympics, but I’m just trying to take it in and pretend it’s Roland-Garros because it’s at that site and it’s in a familiar area. So I think I feel better about that,” says Gauff.

James, 38, is the first men’s basketball player to carry the American flag at the opening ceremony.

After she was selected as Team USA’s flag-bearer, Gauff used social media to thank her fellow athletes for their support.

“I just want to say thank you to my fellow team USA olympians/athletes for voting and choosing me for this incredible honor to be the flag bearer for the opening ceremony,” Gauff wrote in a post on X (formerly known as Twitter) on Wednesday, July 24, adding that she’s “incredibly honored” by the selection.

Gauff’s selection was first reported by Today on Wednesday. Following the announcement, the morning show shared an exclusive video of the moment Gauff was informed and her touching reaction to the honor.

“I was completely shocked,” Gauff said during the segment, adding, “I never would have crossed my mind. I have no words, honestly.”

The athlete continued, “It made me cry. I didn’t want to cry in front of my teammates.. but when I called my mom, I started crying. I think it’s even more special — even now I get emotional thinking about it — that so many incredible people just think that I’m worth of this. It means a lot, truly.”

Live coverage of the opening ceremony starts at 12 p.m. EST on Friday and the event will begin at 1:30 p.m. EST on NBC and Peacock.
