Demi Lovato and her friend, Hanna Beth, are throwing a dual birthday party next week in LA and they posted a sketch of their custom dresses for the special occasion! Isn’t Demi’s dress gorgeous?

Demi Lovato turns 19 this weekend on Aug. 20 and she’s going all out for her big day! The former Disney darling is throwing a joint birthday party with her friend and stylist, Hanna Beth, at a top secret location next week. In fact, they are even getting custom dresses made by designer Marco Marco for what is sure to be a star-studded event.

The dress looks adorable…and similar to the one Demi wore to the Do Something! Awards in Los Angeles Aug. 14. We can’t tell if it’s pink or white, but regardless of the color, it’s definitely going to compliment Demi’s voluptuous figure.

Hopefully this birthday is one of Demi’s best yet. Since turning 18, the multi-talented performer has gone through hell and back — even spending time at a treatment facility for emotional and physical issues. Now, she’s ready to make her big comeback with her album, Unbroken, which drops Sept. 20.

Who do YOU think will come to Demi’s birthday bash? Will Selena and Justin make an appearance? Sound off below!
