The megastar, 34, who recently wrapped her whirlwind tour of Australia, was seen coughing as she performed her hit song Delicate at National Stadium on Saturday evening.
Fans have grown concerned this could be a sign Swift will cancel the rest of her Eras world tour due to sickness.
@heyjoshd hope she’s okay. she’s been coughing 🥹 #TheErasTour #TheErasTourSG #TaylorSwift
‘She looks like she’s not feeling her best… girl needs some rest,’ one wrote, while another added: ‘She should cancel the rest of the shows for health reasons.’
‘She needs a break,’ another lamented, as someone else agreed: ‘Tour is taking a toll on her health.’
Swift is due to perform three more shows in Singapore before flying to France to continue her global tour.
It comes as Southeast Asia Swifties have grown enraged over Swift performing only one stop in the area under controversial circumstances.
Singapore is Swift’s only stop in South-East Asia, after it was reported the country is paying the pop star $4.3million per show to perform there exclusively.
‘Singapore paid a hefty amount so that NO other South-East Asian country can have their chances,’ complained a fan on social media.
‘Should boycott Singapore and Taylor,’ wrote another.
‘Typical Singaporean behaviour, they would do anything to get one up on their neighbours,’ complained another.
Swift’s grant from the Singapore Tourism Board to bring her tour to the wealthy nation sparked a row between the neighboring countries.
Thailand’s Prime Minister Srettha Thavisin last month accused Singapore of paying Swift millions per concert to secure her exclusively, something he found out after the deal was cut.
Speaking at the Bangkok iBusiness Forum 2024 Thavisin said ‘The Singaporean government is clever. They told not to hold any other shows in Asia.’
The Thai PM called Singapore’s move ‘astute’, adding he’d long wondered why Swift had not opted to play in Thailand.
The Singaporean shows will likely be a boom to the economy. Swift has sold out six nights at the 55,000-seat National Stadium this month.
