Fresh off winning her fourth career French Open title, world No. 1 women’s tennis player Iga Świątek celebrated at one of Taylor Swift’s Eras Tour concerts.

The 23-year-old superstar from Poland took to X on Friday to share a photo of a letter she received from Swift at the show:

Świątek showed her appreciation for the global pop sensation and noted that she “cried many times” during the concert.

Since winning her first Grand Slam title in 2020, Świątek has been the dominant force in women’s tennis, winning five Grand Slams in total.

In addition to winning the French Open in four of the past five years, she also won the 2022 U.S. Open, and she was a semifinalist at the Australian Open that same year.

Over the past year, Swift has become a huge topic within the sports world, which wasn’t the case for much of her career previously.

Swift began dating Kansas City Chiefs tight end Travis Kelce last year, and she was seen in the crowd for the majority of Kansas City’s games, which put even more eyes on the NFL product than usual.

She may have been a good luck charm as well given that Kelce and the Chiefs won their second consecutive Super Bowl with her in attendance.

Świątek will undoubtedly take any of the good karma that comes along with her Swift fandom, especially ahead of the Grand Slam that has given her the most trouble during her career.

Wimbledon starts next month, and it is an event at which Świątek has never advanced past the quarterfinals.

If she can find a way to conquer her past Wimbledon demons and win it all at All England Club this year, Świątek will be an Australian Open win away from the career Grand Slam.
