Taylor Swift Wins Big at iHeartRadio Music Awards, Thanks Boyfriend Calvin Harris

— -- It was a good night for Taylor Swift and her pals at the iHeartRadio Music Awards in Los Angeles.

Swift won three awards, including "Album of the Year" for her hit record "1989" and "Female Artist of the Year."

She was also recognized with the "Best Tour" award. The "Shake it Off" singer used the opportunity to acknowledge her boyfriend, DJ Calvin Harris.

"For the first time I had the most amazing person to come home to when the spotlight went out and the crowds were all gone," Swift said. "So, I want to thank my boyfriend Adam for that."

Harris' birth name is Adam Wiles.

The "Best Tour" award was presented to the the 26-year-old singer by Justin Timberlake, who made a joke at Donald Trump's expense, saying, "Some people are out here to build walls...we ain't namin' no names."

Timberlake then snarkily told the largely underage audience, "Shut up...you can't even vote."

Harris himself won an award for "Dance Artist of the Year," while Swift's good friend Selena Gomez was named "Biggest Triple Threat."

Justin Bieber, sporting a hockey jersey, tattered jeans, and dreadlocks, earned the prize for Male Artist of the Year. "I've experienced some tough times -- I think all of us do -- but it's about just our growth and learning," he commented.

Adele accepted Song of the Year for "Hello" in a prerecorded message from a concert in the U.K.

U2's Bono and The Edge were on hand to receive the Innovator Award on their band's behalf.
