Tommy Paul had just reached the Round of 16 at the U.S. Open for the first time in his career after a 6-1, 6-0, 3-6, 6-3 win over Alejandro Davidovich Fokina — and he was feeling all the love.

The American has become a favorite in Brooklyn, with young fans lining up to score face time with the 26-year-old star, some more literally than others.

After the match, Paul was seen signing autographs for fans — which included putting his name on some toilet paper.

One fan signaled for Paul to sign his forehead, and after a small shrug, he agreed and smiled.

“That’s an interesting signature there,” one commentator quipped.

“Not sure how long that will last.”

But the next fan down the line requested another obscure piece of paraphernalia, asking Paul, 26, to sign a roll of toilet paper.

And he did, without hesitation.

And while these fans stole the show after the match, another one, 10-year-old Eddy, has shown his support throughout the week on the sidelines.

He was at the forefront of Paul’s comeback against Roman Safiullin in the second round.

Eddy made himself heard every set of the way, yelling out support and tips that earned him the title of Paul’s “good luck charm.”

After the match on Wednesday, Paul ran over to give him a hug, a shirt and an invite back to Friday’s match against Fokina to keep the good luck going.

He did just that, and Paul said how “cool” it was to have him during his first-ever match at Arthur Ashe Stadium.

“I definitely heard him. I think we got him tickets to our box, but he ended up getting better tickets right on the side of the court,” Paul said. “I was definitely hearing him. It was fun. He definitely got louder after I lost the third, which was cool. I went and talked to him a little bit after, but it’s really cool to have him here.

“I’m hoping he becomes famous or something.”
