Taylor Swift and Travis Kelce are officially engaged.

The popstar and NFL star shared the joyous news in an Instagram post Tuesday, writing in the caption, "Your English teacher and your gym teacher are getting married."

The post included several photos from the couple's engagement, including a snap of Kelce down on one knee. In the photos, the two are seen standing in a garden, surrounded by flowers, with Swift wearing a striped summer dress and Kelce in a dark blue collard shirt and white shorts. The post also included a photo of Swift's ring, a large radiant-cut stone set in a simple band.
