Jessie J - Grammys 2012 Red Carpet

Jessie J sparkles on the red carpet at the 2012 Grammy Awards held at Staples Center on Sunday (February 12) in Los Angeles.

The 23-year-old British singer wore a stunning Julien Macdonald creation.

Jessie sang at Clive Davis‘ pre-Grammy Awards party last night. She belted out her hit, “Who You Are” in honor of Whitney Houston, who passed away yesterday. Jessie is a huge fan of Whitney‘s music and her song “Domino” was inspired by Whitney herself!
