The pop superstar – who has just wrapped the highest-grossing tour of all time with The Eras Tour – took home 10 more prizes at the star-studded bash at the MGM Grand Garden Arena in Las Vegas.
Taylor's haul included Top Artist, Top Female Artist, Top Billboard 200, Top Billboard 200 Album for 'The Tortured Poets Department', Top Hot 100 Artist, Top Hot 100 Songwriter, Top Radio Songs Artist, Top Billboard 200 Global Artist, Top Billboard Global (excluding US) Artist, and Top Streaming Songs Artist.
Having been tied with Drake with 39 prizes apiece, Taylor toppled the rap superstar with her new total of 49 BBMAs, while he picked up three more prizes on the night for Top Rap Artist, Top Rap Male Artist, and Top Rap Album for 'For All the Dogs'.
Taylor thanked her fans and said her record-breaking wins were the "nicest early birthday present", as the Cruel Summer hitmaker celebrates her 35th birthday on Friday.
In a video message, Taylor said: "Thank you to the Billboard Awards. Thank you to the fans, 'cause Billboard is counting your stuff.
"They're counting what you listen to, the albums that you're passionate about, and so I count these as like fan voted awards because you guys are the ones who care about our albums and come see us in concert."
She continued: "Everything that has happened with The Eras Tour and The Tortured Poets Department, I just have to say thank you. It means the world to me that you guys have embraced the things I have made, you know? And the fact that you've cared so much about my music.
"This is the nicest early birthday present you could have given me. So, thank you very much, I love it. It's exactly what I wanted."
The ceremony was hosted by actress and comedian Michelle Buteau and saw performances from Megan Moroney, Jelly Roll and Shaboozey.
