LOS ANGELES, March 4, (Agencies): Barry Keoghan is solidifying his reputation as the ideal supportive partner. The 31-year-old Saltburn star was spotted in the audience at the Eras Tour in Singapore on Sunday, where he attentively watched Sabrina Carpenter's performance at the Singapore National Stadium in Kallang.

In a swiftly circulating video on X (formerly Twitter), Keoghan observed Carpenter, 24, as she sang the outro of her hit "Nonsense," known for its improvised lyrics tailored to the performance's location. Covering his mouth with his VIP lanyard, Keoghan attentively absorbed Carpenter's cheeky ad-lib, which cleverly referenced Singapore's iconic indoor waterfall at Jewel Changi shopping mall. Upon hearing the lyrics, he broke into a smile and enthusiastically raised his hands in applause.

There were also reports suggesting that the actor was present at Taylor Swift's inaugural show in Singapore on Saturday, supported by a photo circulating on X. Keoghan's attendance at Carpenter's performance as the opening act for Swift's record-breaking Eras Tour marks another public appearance in a series of outings, fueling speculation about a potential romance between the two.

In a recent social media post, the "Feather" singer expressed her excitement about performing alongside Swift during the show's acoustic set, a sentiment that garnered Keoghan's acknowledgment as he "liked" the post. The couple's public appearances and online interactions continue to capture the attention of fans, adding an extra layer of intrigue to their rumored relationship.
