Meghan Markle is a Swiftie!

A source confirms to PEOPLE that the Duchess of Sussex, 42, attended Taylor Swift’s performance at Los Angeles’ SoFi Stadium on Tuesday during the Eras Tour’s California leg.

As Swift launched into her Fearless era — telling the excited crowd, “Let’s go back to high school!” — Meghan jumped up out of her chair to sing along to “You Belong with Me.”

Page Six, which was first to report the news, said Meghan attended with her friend Lucy Fraser.

Although Prince Harry did not join his wife as he’s overseas, he’s been to SoFi Stadium since they located to Meghan’s home state in 2020 after stepping back from their royal roles. In 2022, he attended the Super Bowl at the venue alongside his cousin Princess Eugenie, who was visiting from the U.K.

Meghan’s night out came as Prince Harry spends time in Asia. On Tuesday, the Duke of Sussex, 38, was filmed arriving at Haneda Airport in Japan ahead of Wednesday’s ISPS Sports Values Summit-Special Edition in Tokyo. He was joined by his friend and polo star Ignacio “Nacho” Figueras, who is also participating in the summit.

Prince Harry will next travel to Singapore for the 2023 Sentebale ISPS Handa Polo Cup on Saturday. King Charles’ younger son launched Sentebale with Prince Seeiso of Lesotho in 2006 to help children and young people affected by poverty, inequality, and HIV/AIDS in Africa. Since 2010, the annual polo game has raised over $14 million for the organization’s work.

Prince Harry will trot onto the pitch this weekend to play on the Royal Salute Sentebale Team at the Singapore Polo Club. Meanwhile, Figueras, a longstanding Sentebale ambassador, will captain the Singapore Polo Club Team. The equestrian event will mark a return to familiar turf, as the Sentebale Royal Salute Polo Cup (as it was known at the time) was held at the Singapore Polo Club in 2017.

The time apart comes just four days after the couple celebrated Meghan’s 42nd birthday and almost a week after they stepped out for dinner at Tre Lune in Montecito, not far from their California home.
