Fresh off her first US headlining gig on at Los Angeles’ Roxy Theatre, Jessie J was back on stage on Wednesday night (April 11) for the Third Annual ELLE Women In Music event at Avalon nightclub in Hollywood. (If you recall, the mag honored Swedish siren Robyn back in 2011.) The Glamour girl spiced up her rendition of “Price Tag” with help from a fan whom she pulled on stage, making him dance on a platform for the duration of the song. Adding to evening’s celebration, Jessie got to hang backstage with will.i.am, tweeting a photo with the caption,”Will.I.who? Chilling with my ‘cat’ Will”. Speaking of “cats” check out the pop star, back in a skintight catsuit once again, for her WIM performance.
