Taylor Swift may be pop music royalty, but actual royalty turned up at one of her Singapore shows at the National Stadium.

Tunku Idris Iskandar, the younger son of Sultan Ibrahim Iskandar of Johor (currently Malaysia's Agong), shared a series of photos on his Instagram account on Mar. 3, 2024, that showed him taking in the sights and sounds of a special Swift show.

The first photo he shared on his Instagram account was of a fan's The Eras Tour shirt, with the locations of shows in the U.S. and elsewhere.

The second was a moody, greyscale photo of the prince looking out over the crowds gathered to watch Swift perform.

Next, he shared a photo of himself and Minister for Culture, Community and Youth Edwin Tong inside the National Stadium.

The prince also made a cheeky reference to Singapore's next possible superstar attraction, Beyoncé's Renaissance tour.

Tunku Idris is the third child and second son of the royal family of Johor.

His elder brother, Tunku Ismail Idris, is the Crown Prince of Johor.

Tunku Ismail Idris officially became the Regent of Johor earlier this year, as his father became the Yang di-Pertuan Agong of Malaysia on Jan. 31, 2024.
