Apart from her aqua hairstyle, the "Heart Attack" singer went for a darker look with black heels, leggings, and a black blazer at the party. The former Disney star is known for being outspoken and fearless when it comes to her personal style. 

Lovato is currently judging Season 3 of the U.S. version of The X Factor along with Simon Cowell, Kelly Rowland, and Paulina Rubio, and is also playing Santana's love interest Dani on Season 5 of Glee. Lovato has signed on for six episodes of the hit Fox musical comedy, which aired its touching Cory Monteith tribute episode, "The Quarterback," on Oct. 10.

But she doesn't regret the decision to sign on to the Fox competition show's judging panel. In September 2013 she told Billboard, "When you have the opportunity to be in front of America every single week several times a week, that's a very incredible opportunity, not only because your fans get to know you better, but it's really awesome to have expanded my fan base."
