Demi Lovato is certainly in the mood for another hair change! The singer and "X-Factor" judge showed off her new hair style and color via her Twitter account.

After she slightly surprised everyone with a hot pink hair in time for her "Neon Lights" tour, it only took a short time before she got bored and came up with a half shaved hairstyle, E!Online reports. With her edgy new look, she did not miss out on giving a caption as carefree as her hair: "IDGAF #NEONLIGHTSTOUR."

A subsequent picture was also posted by the young star with a corresponding message that says, "So... This happened... Oops." It then showed the razor she used and the hair that was shaved off.

According to Daily Mail UK, Demi debuted her rockin' pink hair during the Grammy Awards in February. The singer is currently traveling for her mentioned tour which started off in Vancouver last February 9. Her tour's opening acts are all female artists namely the Little Mix and Fifth Harmony. However, from March 20 to 30, it will be Cher Lloyd who will take over as her front act.

Demi has been very open with her life and eccentric side. She even had her own share of troubles including checking into a rehab and now returns back as a success maintaining a clean way of living. She even mentioned in one interview with "Extra" how she wants everyone in her team to "stay clean and focused" and avoid much of the usual partying.

On the other hand, Hollywood Life wonders how the 21-year-old singer's boyfriend will take her new look? Demi's hunk boyfriend Wilmer Valderrama was spotted with the "Heart Attack" singer dining together at the Magnolia South Café on January 29, looking happy.

Another celebrity who took the risk of changing her hair color is Nicole Richie who reportedly dyed her hair color similar to the violet hair of Kelly Osbourne, Hello Magazine wrote.
