Alcaraz and Sinner 'Both Dating Same model' in Awkward Love Triangle

A source has claimed Carlos Alcaraz and Jannik Sinner were both dating the same model during the 2025 US Open.

Alcaraz added his second US Open title to his trophy cabinet with a 6-2, 3-6, 6-1 and 6-4 victory over the Italian in New York.

Victory was the sixth Grand Slam of his career and also meant he wrestled back the world no.1 spot away from Sinner who last defeated the Spaniard in the Wimbledon final back in July.

“I give 100% every day to improve, sitting down with the team to see what I can do better to beat Jannik and win these kind of trophies," Alcaraz said.

"Having this rivalry means a lot - it is super special for me, for him and for the people who enjoy every it single time we play."

Alcaraz has also been making headlines off the court after putting rumours of a romantic spark with fellow tennis star Emma Raducanu to bed after it emerged he was in a relationship with Sports Illustrated model Brooks Nader.

Nader had previously been romantically linked to Alcaraz’s rival Sinner and a shocking report has revealed an eye-opening plot twist on their new relationship.

Page Six claim Nader was dating BOTH of the tennis stars at the same time at the time of the tournament.

Nader was spotted on the front row to watch Alcaraz defeat Arthur Rinderknech on August 31.

The 28-year-old was previously married to real estate investor Billy Haire before the pair divorced earlier this year. She also casually dated NFL superstar Tom Brady.

SPORTbible have contacted Nader’s representatives for comment.

Confusion over Alcaraz’s relationship status

Alcaraz’s relationship with Nader was confirmed by her older sister Grace Ann who told E! News that ‘he is the man of the hour’.

However, journalist Alberto Guzman has refuted her claims and believes the pair are NOT an item.

He appeared on Spanish TV to shoot down the rumours and claimed Grace Ann might be out of the loop.

“They're not dating, it's not an official relationship,” he said, via 20 Minutos.

“He [Alcaraz] confirmed to those close to him that he is single and has no intention of having any serious relationships.”

On Grace Ann, he said: “Perhaps she is not well informed.”

Alcaraz was selected to feature for Spain in the Davis Cup qualifier this week but decided to withdraw from the tournament.
