Several of the couple’s friends were also in attendance, including Lana Del Rey, Zoë Kravitz and Channing Tatum and Swift’s tour mate Sabrina Carpenter and her rumored boyfriend Barry Keoghan, who also recently attended the Eras Tour in Singapore.

The pop superstar and three-time Super Bowl champion’s post-Oscars outing comes off the heels of Swift’s six-night Eras Tour run in Singapore.

Before the “Cruel Summer” singer’s string of sold-out shows wrapped up on Saturday, Kelce traveled to attend the fifth and sixth nights.

During night five, Swift gave a sweet nod to her boyfriend in the crowd, as she changed the lyrics of her Midnights hit “Karma” to give him a shout out by singing, per fan videos, “Karma is the guy on the Chiefs coming straight home to me.”

While in Singapore, the pair was spotted spending quality time together. Fans captured footage of the two enjoying a casual date night out a mall.

After the shows — which marked the end of the Eras Tour’s leg across Australia, New Zealand and Asian — Swift took to Instagram to express her gratitude for the success of her six-night residency. “We got to play 6 shows in Singapore for the most wonderful crowds — just want to say thank you from the bottom of my heart to everyone who traveled and put so much effort into being at our shows,” the “Anti-Hero” singer wrote. “What an unforgettable way to end this leg of the tour!!”
