"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, in stadiums all around our world," Timberlake said on stage. "From the start, this talented singer, songwriter and performer born in 1989 has been elevating the place of music in our lives. Breaking world records as a recording artist and bringing all types of people together in big and little ways as a touring sensation. She has won over 250 awards to date I don't know how that is mathematically possible."
We're not sure either, but it's insanely impressive!
Swift's thank-you speech was even sweeter while simultaneously taking a dig at all her less-than-stellar exes. "For the first time, I had the most amazing person to come home to when the spotlight went out and when the crowds were all gone, so I want to thank my boyfriend, Adam, for that."
No, she hasn't broken up with Calvin Harris -- the DJ's real name is Adam Richard Wiles -- and she walked hand-in-hand with him into the award ceremony, like the adorable duo that they very much still are. Seriously, look how happy was when Swift won her first award of the night:
The 32-year-old DJ and record producer also went home with a win for Dance Artist of the Year, though he did not remember to thank Swift when in his speech. Whoops! At least the two gave each other a massive hug before he hit the stage. And, hey, he did give remember to give her a shout-out after her GRAMMY wins.
Let's also not forget to point out the fact that Swift looked absolutely fierce in her sequined halter Saint Laurent jumpsuit and belt, which she paired with Giuseppe Zanotti shoes, Vhernier earrings and ring, and a pave Melinda Maria Jewelry band.
Inside the show, Selena Gomez sat with her BFF Swift and Harris, and she wasn't a slouch in the nominations department either. She nabbed the Triple Threat award, but ultimately lost to Swift in the Female Artist of the Year category -- but graciously embraced her pal to congratulate Swift on the win. She was also up for Triple Threat and Best Fan Army.
Gomez even got to present her BFF with an award, handing out the Album of the Year trophy to "my girl T. Swizzy" for 1989.
"I want to thank all the radio stations who played the songs off of 1989," Swift gushed in her acceptance speech. "I never dreamed of having that many number ones. Thank you for liking and listening to my songs on the radio, that’s really nice."
The singer also took a moment to thank her family, adding that the iHeartRadio Awards might be her "last awards show for a while."
"My most vivid memory of growing up is my mom and dad telling me that I was different and unique and special and that I could do whatever I wanted with my life," she recalled. "So parents, tell your kids every day that they’re different and they’re special, they’re unique, they can do whatever they want with their lives."
Swift and Harris just celebrated their one-year anniversary last month, and they celebrated by going on a tropical vacation that totally defined #RelationshipGoals for all of us. Take a peek at the adorable photos from their getaway:
