Jessie J jetted from Heathrow to Hollywood, hitting the outdoor stage on “Jimmy Kimmel Live!” on Monday (April 18). Dressed in a lacy leotard with caged dress and heeled boots, she once again performed her hit “Price Tag” and follow-up “Nobody’s Perfect” from her debut album Who You Are. The big-voiced Brit has been added to the lineup for England’s Big Chill festival in August, along with Kanye West.
