Alcaraz, Djokovic, Swiatek and more watch Rafael Nadal vs. Alexander Zverev in Paris

The highly-anticipated Roland Garros first-round match netween 14-time tournament champion Rafael Nadal and No. 4 seed Alexander Zverev brought the star power in the stands, too.

Carlos Alcaraz, Novak Djokovic and Iga Swiatek were among the thousands who crammed into the seats on Court Philippe-Chatrier on Monday in Paris to watch the 37-year-old Spaniard play possibly (or not, depending on how you viewed his declaration in his pre-ever press conference) his final match on the court he once famously dominated.

Meeting the media for his pre-tournament press conference on Sunday after it was revealed the Nadal and Zverev would duel in Monday's day session, Djokovic told reporters he "definitely" wanted to tune in, and would work around any prior commitments to "catch as much as [he] can."

"I think everyone will want to see what will happen," the No. 1 said with a grin.

Himself included, as it turned out.

Swiatek seamlessly transitioned from playing on Chatrier to being a spectator after beating France's Leolia Jeanjean in her first match of the tournament.

Speaking to former Wimbledon champion Marion Baroli in her on-court interview, Swiatek—who still hasn't turned in her Nadal fan card despite competing alongside him—said "for sure" she'd be watching.

"He's a great person, great athlete, and he has shown that for many, many years ... I'll do my best to take some lessons from him to be a great person and a great player."

Alcaraz, meanwhile, was on Chatrier for a second consecutive day after beating American J.J. Wolf on Paris' main court on Sunday.

Making no secret of his desire to play doubles with Nadal when tennis returns to Paris for the Olympics in three months' time, Alcaraz has been plugged into his legendary countryman's status.

"All I want to be focused on is to enjoy his last tournament as much as he can play," Alcaraz said on the eve of the tournament. "I want to enjoy his tennis, but obviously everything comes to an end, but honestly, I don't want to see him retiring soon or playing his last tournaments."

A place he did want to see him, though? On Chatrier.

But major champions weren't the only famous faces in the crowd for the match. Spanish singer Raphael, soccer star Rodri, former Roland Garros finalist Henri Leconte, and Emily in Parisstar Lucas Bravo were also in the stands.
