Several Artists Added To Billboard Music Awards Line-Up

Kelly Clarkson, Ed Sheeran, Meghan Trainor and John Legend are officially confirmed performers at the 2015 Billboard Music Awards.

The line-up is already insane, including performances from Fall Out Boy (“Uma Thurman”), Hozier, Wiz Khalifa, Nick Jonas, Sam Smith and rumor has it Britney Spears and Iggy Azalea (“Pretty Girls”)!

From Billboard:

Taylor Swift leads the pack with 14 nominations in 13 categories, though she’s closely followed by Sam Smith (13), Iggy Azalea (12) and Meghan Trainor (nine). The full list of finalists was unveiled earlier this month.

The 2015 Billboard Music Awards air on ABC on May 17 at 8pm ET at the MGM in Vegas.
