Demi Lovato Stuns with Aqua Blue Hair on the Red Carpet

Demi Lovato stepped out for the first time since she dyed her hair blue to attend Glamour Magazine's 15th Anniversary party on Oct. 10 in Mexico City, Us Weekly reported.

Lovato performed with the new hairdo on The Tonight Show With Jay Leno on Oct. 2 but this was the first red carpet of the star where she appeared with her newly dyed hair.

Aside from her aqua hairstyle, the Heart Attack" singer also went for a gothic look with black heels, leggings and a black blazer at the party. The singer is known for being opinionated and daring when it comes to her personal style.

Lovato is currently a judge at the U.S. version of The X Factor together with Simon Cowell, Paulina Rubio and Kelly Rowland. In addition to that, the former Disney star is also playing the love interest of Santana on Season 5 of Glee. Lovato has signed on for six episodes of the hit Fox series.

The artist recently announced that she is going on tour with British pop star Cherly Lloyd, the Brit girl group Little Mix and X Factor finalist group Fifth Harmony. The tour will start in February 2014. Because of her X Factor filming schedule, she hasn't been able to promote her latest album, Demi.

However, she said that she doesn't regret the decision to sign on to The X Factor. 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."
