Demi Lovato is all about life changes lately!

The 19-year-old singer changed her hair color over the weekend -- to red! She Tweeted the pic above on Sunday, saying, "Red hurr she don't curr..."

DemiLovatoLatinaCover230.jpgLovato recently gave an interview to Latina magazine and about her stint in rehab (although we have to ask -- what is left to say?) She told the mag she was afraid she wouldn't have a career after spending time in a facility, and that rehab wasn't totally her idea.

"It was influenced by management, publicists and family," she said. But one person who didn't help was her estranged father. "Sometimes there are people in your life that you have to cut out," she says. "It sucks when it’s your own father."

And did Demi hint at rekindling her relationship with her much older ex Wilmer Valderrama, 31? The two were spotted smooching last week.

"I have an old soul, because I had to grow up fast – because of the public eye and because of my life experiences," she said.
