Demi Lovato appears on the cover of the August issue of Self. It's her birthday month -- she'll be 20 on Aug. 20 -- and what a way to celebrate. The ish doesn't hit stands until next week but you can take a peek of the bright and sunny cover image of the singer and new 'X Factor' judge, since it has leaked.

The cover features a summery shot of Lovato, with sunkissed skin and her mega long and lightened-to-blonde beachy waves tumbling all around her face while she balances a big blue beach ball behind her head and shoulders. Even though her thick waves frame her face, she gives off a gorgeous smile, boasting lips with a whisper light hint of peachy pink gloss, too.

Did you notice how absolutely bangin' the 'Give Your Heart a Break' singer's body is, as well? She is poured into that lemon yellow, strapless and figure-hugging frock. Her booty is looking mighty fine as well.

Perhaps Lovatics should photobomb One Direction member Niall Horan's Facebook and Twitter with this image, since there have been so many rumors of a mutual crush between Demz and Niall. This shot could make his knees buckle.

Lovatics should tune into 'Good Morning America' tomorrow, when the teen will perform a three-song set as part of the breakfast TV program's summer concert series. Lovato will sing 'Give Your Heart a Break,' 'Skyscraper' and 'Unbroken.' A wonderful way to start the weekend, right?
