Jessie J celebrates with the Deluxe edition of her album!

You'd be pretty chuffed if you had the best selling debut album of the year, wouldn't you? For Jessie J, beginning the year with all that hype, all those expectations, who'd have thought that the final few months would bring affirmation of just how successful she's been.

Yup, that's right - Jessie J's debut LP Who You Are is officially the best-selling debut album of 2011. Getting that all-important first album right is crucial and as many would say, you can't argue with the sales. Jessie's been a hands-down success and her performance on this weekend's X Factor will see the culmination of that.

If you haven't already got a copy of Jessie J's album, or if you already do and fancy more, the Deluxe edition is out now, featuring a bonus live DVD and a number of extra tracks:

Domino
Laser (Produced by David Guetta)
My Shadow
Technology (Acoustic)

Jessie J - Abracadabra

If any of the tracks on Jessie J's debut album Who You Are stand out the most, it is this one. I love the chilled 90s R&B vibe to the whole thing. It's classy, well produced and shows Jessie's vocals and songwriting talent at its best. Remembering that Jessie co-wrote Miley Cyrus's Party in the USA, it is Abracadabra that sounds most similar out of her solo material, the chorus in particular sharing that vibe of sun-kissed bliss and youthful energy. It's a big feel-good anthem and would make a great future single.

Jessie J - Who You Are

After the mega-success of Do It Like A Dude, it goes without saying that Jessie J's debut album Who You Are will be one of the year's must-buys. We're loving the album cover, where Jessie shows that no-one in pop rocks the razor-sharp fringe as well as she does. The all black look is rather cool too, especially the lippy.

In terms of Jessie's music, Price Tag is one of our definite faves from the album and features American rapper B.O.B.
