Taylor Swift, Justin Timberlake Have Mutual Lovefest in Post 2016 iHeartRadio Music Awards Instagrams

Nothing to get jealous about, Calvin! Taylor Swift and Justin Timberlake are really, really huge fans of each other.

The "Shake It Off" singer was presented with her Best Tour gong at the 2016 iHeartRadio Music Awards by the former 'N Sync hunk on Sunday, April 3. And it was clear from Timberlake's cute onstage tribute that he's got a whole lot of respect for Swift.

"I am very happy to be back with all of you in this arena to help honor a great young woman who has accomplished extraordinary things in arenas and stadiums all around our world,” he said. “This extraordinary singer, songwriter and performer has been elevating the place of music in our lives, bringing all types of people together in big and powerful ways as a touring sensation. She has won over 250 awards to date. I don't know how that's mathematically possible," the 35-year-old singer enthused about Swift, 26.

But the duo waited until after the show to display the true depths of their affection for one another, when they took to Instagram to share a couple of really sappy messages!

Timberlake was first, sharing a photograph of Swift on stage, accepting her award, taken from behind (and showing off the amazing back view of her black sequin jumpsuit!).

"My good friend, Taylor … Congrats, dear!!! #iHeartAwards," the show presenter captioned his pic.

Two hours later, and evidently overwhelmed by her hero's public display of affection, Swift returned the favor, sharing a cute black-and-white snap of the pair of them backstage at the show.
