The 25-year-old superstar won eight awards at the ceremony held at Las Vegas' MGM Grand Garden Arena last night (17.05.15), including Top Artist, Top Female Artist and Top Billboard 200 Album for '1989', and said she had ''such a good night''.
Picking up the Chart Achievement Award, Taylor said: ''I wanna shout out of course to Iggy [Azalea] and Meghan [Trainor] because they're amazing, I'm just happy to be in the same category. This is such a good night. What EVEN!''
The 'I Knew You Were Trouble' hitmaker spent the night cuddling up to her boyfriend Calvin Harris - who won Top Dance/Electronic Artist - and also took the Billboard Awards as a chance to show off the star-studded video for her new single 'Bad Blood'.
The video features Lena Dunham, Kendrick Lamar, Oscar nominee Hailee Steinfeld, and models Cara Delavingne and Gigi Hadid, among others, in a Tarantino-and-Sin City-inspired extravaganza.
In the video, Swift recovers from a betrayal by a warrior buddy played by real-life friend Selena Gomez by going into battle training with a crew that includes many of her model friends. Cindy Crawford is also there to give her seal of approval before Taylor marches into battle.
