The stars are sure shining bright tonight!

It's the 56th Annual Grammy Awards, and music's biggest names are hitting the Staples Center in Los Angeles in their red carpet finest.

Katy Perry looks like a teenage dream in an ethereal note-printed Valentino gown, Hunter Hayes and Austin Mahone suit up in Tom Ford and Sanctuary78 (respectively), Colbie Caillat is red-hot in Ezra Santos and Paris Hilton's see-through Haus of Milani creation has everyone talking!

See who's taking risks and who's turning it out in our 2014 Grammys Arrivals gallery!
