Pop superstar Taylor Swift and National Football League player Travis Kelce are engaged to be married, the couple announced on social media on Tuesday, Reuters reported.

In a joint Instagram post, the pair wrote: "Your English teacher and your gym teacher are getting married," along with photos showing the Kansas City Chiefs player proposing to Swift.

Photos showed the American couple in a garden of pink and white flowers. One image showed Kelce on one knee looking up at Swift, and another featured a large ring on Swift's left hand. A snippet of Swift's song "So High School" played in the background of the post, according to Reuters.
