Stomp, stomp, she’s arrived! Jessie J‘s US promo blitz kicked off in spectacular fashion tonight; for the Essex-bred star took centre-stage on the iconic Saturday Night Live.

Assisted by rapper B.O.B, the 22 year old served up a rousing rendition of their British chart-topper ‘Price Tag’, as well as ‘Mamma Knows Best’ – both lifted from her debut LP ‘Who You Are’.

Check out all the action after the jump…

Needless to say, Jessie nailed it effortlessly. Great performances.
