Tayvin fans, prepare yourselves for some impending adorableness!

Taylor Swift and boyfriend Calvin Harris are -- obviously -- seated next to each other at the iHeartRadio Music Awards on Sunday, which means if the "Blank Space" singer wins any of the seven categories that she's nominated in, the couple will probably bless us with another sweet hug. Maybe they'll even upgrade to a celebratory kiss!

The bigger question mark of the night is whether there will be a Jelena reunion.

Selena Gomez stepped out to support her ex, Justin Bieber, during his Purpose Tour stop in Los Angeles last week, but as far as the seating chart is concerned, the pop stars won't be getting too close. Selena is sitting with BFF Swift, while the Biebs is seated one table away.

That said, the only thing separating them is Justin Timberlake, Ryan Seacrest, and Meghan Trainor. The "What Do You Mean?" singer will sit with Chris Brown and Demi Lovato -- the sometimes bestie of Swift and Gomez, which should be v v interesting.

Zayn Malik and Iggy Azalea will also be in attendance and both have seemingly requested plus ones. Will this be the red carpet debut of Zayn and girlfriend Gigi Hadid? More importantly, will Iggy show up with fiancé Nick Young amid his cheating rumors?

This could be one seriously dramatic awards show...

The iHeartRadio Music Awards airs on TNT, TBS and TRU TV at 8/7c.

Check out Iggy's latest comments on gossip about her fiancé -- and find out why she's "not tryna marry a cheater" -- in the video below.
