Billboard Music Awards 2015: Nick Jonas & Girlfriend Olivia Culpo Pair Up On The Red Carpet

Before he performed his hit single “Jealous” at the Billboard Music Awards, Nick Jonas escorted model girlfriend Olivia Culpo down the red carpet at the Las Vegas shindig. You may recall that the pair were somewhat inseparable while attending last month’s Radio Disney Music Awards.

Nick was decked out in head-to-toe purple, while Olivia wore a formal black romper that revealed more than a bit of skin.
