They’ve been dating for a year now, and last night Taylor Swift gushed about boyfriend Calvin Harris at the iHeartRadio Music Awards.

It was a pretty successful night for the pair, with Taylor picking up FOUR awards, including Best Female Artist and Album of the Year, while Calvin nabbed the title of Dance Artist of the Year.

But it was during her Best Tour award speech that Swifty gave a cute shoutout to Calvin, real name Adam Wiles, thanking him for being amazing.

She said: “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 and I love you guys so much.”

Taylor went on to pick up the Best Female Artist and Most Meme-able Moment (for ‘Crazy Girl’ from her ‘Blank Space’ video) awards.

Sharing some words of wisdom as she took to the stage to collect the Album of the Year award for ‘1989′, Swifty told the audience: “I know my mum, dad and brother are watching and my most vivid memory of growing up is my mum and dad telling me that I was different and unique and special.

Watch her while she does her thing! Though all eyes were on Iggy Azalea's still-there engagement ring when she walked the red carpet at the iHeartRadio Music Awards, the Australian rapper turned the focus back to her music once the show started.

Performing her latest single, "Team," Azalea hit the stage in a blue bra and loose pants and showed off her insanely toned abs as she danced.

Imitating her newly-released music video for the song, her backup dancers grooved in front of a giant airplane backdrop. Following her performance, Azalea rushed backstage where she was greeted by pal Demi Lovato, stopping to pose for pics.

Earlier in the evening, the 25-year-old emcee opened up to ET about her plans for the night with the "Stone Cold" singer.

"We're going to sit together. We're messing up the seating arrangement," Azalea said of Lovato, who is also one of her bridesmaids. "You had us so far apart! I don't know who was thinking that was a good idea. Obviously, the girls need to be together. I think it's more fun to make it like a girls' thing or a friends' thing. It's just more fun, more laughs."

Azalea seemingly enjoyed her much-needed fun night out after her personal life made headlines last week. Her fiancé, Nick Young, was the subject of cheating rumors after a private video of him talking to his Lakers teammate D'Angelo Russell surfaced. Azalea has tweeted several times about the incident, never clarifying the status of her relationship, but on Sunday night she wore her diamond engagement ring on the red carpet despite leaving Young at home.
