British singer-songwriter Jessie J is getting down ‘n’ dirty in the official music video for her debut single Do It Like a Dude.

This video comes across as quite scary, as Jessie goes for a Marilyn Mason look – complete with the freakiest lipstick I have ever seen. This is actually the first time I have heard the original version of Do It Like A Dude, and I have to say that I much prefer the Labrinth remix!

Hit the jump for Jessie’s performance last night on Jools Holland, where she performs a confident acoustic version of her song Price Tag (and she looks normal).
