Just a few hours before singing sensation Whitney Houston’s untimely death, gorgeous young starlet Demi Lovato debuted her new blonde locks on Twitter.

After tweeting exchanges with fans about her new look ("Thank you SO much Nine Zero One salon for my new locks!! How do you guys like the new look??"), her fans were quick to respond. They even got the topic, "Demi Blondevato," trending on the social media site.

After hearing the news about Houston, however, Lovato's tone changed. “This can’t be true," she wrote, "One of my idols gone??” Lovato went on, “This is so unbelievably sad…#RIPWhitneyHouston.”
