Sleuthing Swifties are convinced that Travis Kelce proposed to Taylor Swift right after the pop star appeared on his “New Heights” podcast earlier this month.

The “Love Story” singer guest-starred on the podcast the NFL star co-hosts with his brother, Jason Kelce, in a record-shattering, over-2-hour episode on Aug. 13.

This Tuesday — nearly two weeks after Swift announced her upcoming 12th studio album, “The Life of a Showgirl,” on the podcast — the couple confirmed their engagement on Instagram.

“Your English teacher and your gym teacher are getting married 🧨,” they captioned a joint post, featuring images of the beautiful proposal as well as Swift’s old mine brilliant-cut diamond ring set in a gold bezel (which was co-designed by Travis and Artifex Fine Jewelry’s Kindred Lubeck).

Shortly after, Page Six exclusively confirmed that Travis popped the question “a couple weeks ago” and the duo had been keeping it a secret.

When it comes to theories about the proposal unfolding after the podcast episode premiere, the timeline certainly adds up.

The location of their engagement also aligns with fan speculation as Travis got down on one knee in his own backyard at his Leawood, Kan., estate. This is a key detail, as Travis typically records the podcast from his Kansas home while Jason remotes in from his mansion in Philadelphia.

Swift’s physical appearance also holds some telling signs that she sat for the episode before becoming Travis’ fiancée.

For one, Swift’s nude manicure from the podcast appeared to be the same set of nails she was rocking when she was presented with her massive rock.

The “Cardigan” artist, 35, also appeared to have indentations in her hair exactly where she was wearing headphones on the Wave Sports + Entertainment show.

“YOU CAN SEE WHERE THE HEADPHONES INDENTED HER HAIR,” one person claimed in an X post while showing side-by-side photos of Swift on the podcast and after she said “yes.”

Eagle-eyed spies noted that Swift was wearing the same diamond-studded Cartier Santos Demoiselle watch when Travis asked for her hand in marriage as when she was on the episode.

“Ok I knew the watch was familiar looking, but I didn’t think she was wearing it again or this was the same day,” an X user said.

Other fans were convinced that Travis, also 35, used the podcast as the perfect cover to keep her distracted as the engagement flowers were being set up — and to make sure that she was in full glam for the subsequent engagement photo shoot.

“Also he needed her distracted so they could set up it all makes so much sense,” an X user said.

“10000% like literally had to plan this on the day of her first podcast and album announcement just so he had a CHANCE of her being surprised,” an internet user agreed.

“But also so considerate of him to do it the same day so she’d be in full professional glam for the engagement photos,” another chimed in.

Reps for Kelce and Swift did not immediately respond to Page Six’s requests for comment.
