JESSIE J ON "SATURDAY NIGHT LIVE"

Jessie J on SNL

Now that's what I call singing Jessie J was devastatingly good on last night's episode of Saturday Night Live as Musical Guest. She performed two tracks off her forthcoming debut Disc Who You Are (due April 12, 2011), Price Tag ft. B.o.B. and Mama Knows Best.

It's not often that an Artist is done justice on that fickle SNL stage, but the fact that Jessie J, let alone be asked to perform as a guest when she doesn't even have an Album out in North America yet is well.... v. impressive. 

Witness the magic below:
