the music video she released -- which she thought was really good -- was called the "worst music video in the history of music videos," and "absolute shit!" among other things. Now she's bringing her sorrow public. USMagazine.com is there:

"I just started sobbing uncontrollably."

"I cried myself to sleep that first night after my video came out. I just couldn't understand why people I didn't even know felt the need to be so cruel and hurtful toward me."

"I am just a 21-year-old from a small town in Colorado trying to follow her dreams."

"We were at the beach and, literally, Spencer had his camera and a boom box in the trunk. We did it in one take, maybe two, and it took us 20 minutes to film and cost us zero dollars."

"We had other ideas but we couldn't afford them."

Heidi cry it off. It's all right now. But if you can't make it on THIS salary than maybe you should try something else. Those studios in the valley are always looking for talent.
