Taylor Swift continued on her quest for world domination during her 1989 Tour Wednesday night.

The 25-year-old singer added Wiz Khalifa to the already long list of stars who have joined her on the tour, bringing the rapper on stage during last night's Houston concert and fangirling just as much as the crowd over his presence.

The duo performed Khalifa's current hit single "See You Again," the song in dedication to Paul Walker from the Furious 7 soundtrack. Of course Swift made sure to uphold the meaning of the song by absolutely killing it.

And I'll tell you all about it when I see you again...

With pyrotechnics and fireworks going off in the background, Swift dazzled in a blue fringed sequin dress while Khalifa donned his go-to white-on-white ensemble in an unbuttoned shirt and jeans.

The two made it appear as though they'd been performing together for years, bringing lots of energy and raising emotions in the crowd. They continued to pull at fans' heartstrings by giving each other a long, emotional hug at the end of the song.

Swift took to Instagram to share a few photos from their performance, including the moment they embraced on stage. The songstress couldn't help but use the opportunity to gush about the rapper, calling him "one of the sweetest and most talented people" she's ever met.

But while the duo's performance may have looked absolutely perfect, the moments after the show weren't entirely smooth sailing. The country-turned-pop crooner shared a video backstage at Minute Maid Park as an alarm began sounding off through the stadium.

"A fire alarm is going off in the stadium and we don't know what to do," Swift captioned her video.

At one point we hear a woman yelling frantically at Swift to "put some damn clothes on," but the singer doesn't listen, arguing that she was wearing a robe.

"This is clothes! I'm covered!" she says, not allowing the alarm to frighten her.

Luckily it appears Swift made it out okay—clothed or not—as she continued to share some behind-the-scenes videos from the night with her followers.

Phew!
