According to reports, Brooks Nader was seeing Jannik Sinner and Carlos Alcaraz

Page Six has a source who claims that Brooks was seeing Jannik Sinner, the No. 1 seed at the US Open, and Carlos Alcaraz, the No. 2 seed, during the competition.

When Brooks' sisters, Mary Holland, Grace Ann, and Sarah Jane Nader, said late last month that she receives direct messages from athletes in "every field imaginable," it was initially assumed that she was seeing Sinner.

Page Six Radio heard Grace Ann say, "Every field and court."

Grace Ann explained, perhaps alluding to a tennis court, "not the NBA court."

Sarah Jane intervened, instructing Grace Ann to withhold further information. Brooks said, "Oh s–t, you guys are making me sweat," in response to the host's further clarification about whether it meant a tennis court.

But Grace Ann kept giving another clue: "It rhymes with winner," so it didn't matter what her sisters said.

Though neither the model nor the tennis pro admitted a romance, fans soon realized that Grace Ann was referring to Sinner.

Jimmy Kimmel asks Brooks Nader about his romantic life.

Jimmy Kimmel, the host of a late-night talk show, questioned the model once again after Brooks' sister talked about her dating life.

"Are you seeing Jannik Sinner, the famous Italian tennis player?" Kimmel inquired about her appearance on Jimmy Kimmel Live on September 2nd!

Would you say that this is an interrogation? Right now, I'm really afraid! Nader answered giddily.

“It is, and you’re under oath,” joked Kimmel.

"Well, find out from Stephen which match we attended. He wasn't playing in that one, in my opinion," Nader remarked. Sinner did not play on Sunday, August 31, and she and the Colberts were watching France's Arthur Rinderknech and Spain's Carlos Alcaraz.

"You're near. She said, "You're warm."

"Oh, I see. Is it someone else? questioned Kimmel.

"You're warm. We weren't present at that game," Nader said.

Although neither Brooks nor Alcaraz has confirmed it, Grace Ann revealed that the two are currently dating.

At Raising Cane's New York Fashion Week event, Grace Ann told E! News, "The rumors are true." "I know he's the man of the hour, but dating is such a vague term."

Since Brooks' man has already met their other two sisters, Grace Ann said that he is "such a cutie" and that she is "dying to" meet him.
