Barry Keoghan Supports Sabrina Carpenter at Taylor Swift's Eras Tour in Singapore

Barry Keoghan is proving to be the ultimate supportive boyfriend.

The Saltburn star, 31, was spotted in the crowd at the Eras Tour in Singapore on Sunday as he watched Sabrina Carpenter perform at the Singapore National Stadium in Kallang.

In a video that quickly circulated on X (formerly Twitter), Keoghan watched Carpenter, 24, sing the outro of her hit “Nonsense” — which she always improvises depending on the location of her performance — as he covered his mouth with his VIP lanyard.

After Carpenter sang her cheeky ad-lib lyrics, which included a reference to the famous indoor waterfall inside Singapore's Jewel Changi shopping mall, Keoghan smiled and immediately raised his hands above his head in applause. 

The actor was also allegedly spotted at Taylor Swift’s first show in Singapore on Saturday, according to a photo that circulated on X.

Keoghan’s trip to see Carpenter perform as the opening act for Swift’s record-breaking Eras Tour is the latest in a string of public appearances that the pair has made together since rumors began circulating of a potential romance between them.

Last week, the “Feather” singer shared a post reflecting on her excitement at performing alongside Swift during the show’s acoustic set, and Keoghan shared some love as he “liked” the post and also left a “👸🏼” in the comment section.

The pair has also been spotted out and about together quite a few times since the year started, first at the Luna Luna art-centric theme park in Los Angeles.

"It definitely seemed like a date,” an onlooker told PEOPLE in January after seeing the duo at Luna Luna.

Keoghan and Carpenter were “cute” together and “shared a little kiss,” the onlooker added.
