Taylor Swift Arrives With Her Best Friends—And Sits With Calvin Harris!—At The 2015 Billboard Music Awards

Girls night! Taylor Swift turned the 2015 Billboard Music Awards into a BFF party on the red carpet, which she walked with some of her famous friends that starred with Taylor in her "Bad Blood" music video.

Before premiering the star-studded video at the beginning of the show, Taylor stunned on the RC in a white one piece with a plunging halter neckline.

And check out that clutch! Tay accessorized with a purse that read "Bad Blood," of course as an ode to her new single and video.

The song is rumored to be about Taylor's feud with Katy Perry—and this look says it all, right?!

And though Taylor and rumored BF Calvin Harris did not walk the red carpet together, the duo were seated next to each other inside the show. They even shared a sweet embrace when Taylor accepted her award for Billboard Top 200 album for 1989!
