The Grammy Awards aren't until Sunday, but the celebrations have already started. Tonight, Katy Perry and Chrissy Teigen both got fancied up to show their support for the MusiCares event honoring Bruce Springsteen. For the special occasion set in LA, Katy looked brighter than ever in an orange mermaid-style halter gown with an embellished collar, while Chrissy chose an exquisite white dress with feather and gold sequin detailing. The model completed her red-carpet ensemble with statement drop earrings and a matching gold clutch, and Katy added shine via Lorraine Schwartz diamond stud earrings and an opal ring. There's no doubt about it: both these ladies pulled out all the stops — Katy brought the color, and Chrissy delivered shine — but which would you crown best-dressed of the night? Vote below.
