Demi Lovato wants to be a role model for teenage girls.

“There was nobody out there for me to look at and say maybe this is unhealthy,” Lovato, who battled eating disorders, says on an episode of the The Ellen DeGeneres Show scheduled to air Tuesday. “I want to be that for a 13-year old girl at home deciding whether or not to eat dinner, or an 18-year-old girl deciding whether or not to keep her breakfast down.”

When Lovato finished treatment, she decided to be outspoken about the pressure she was facing.

“It was the time in the tabloids when very, very skinny girls were on the cover of every magazine, and that’s what I was looking up to,” she says. “That’s what I had to idolize. I don’t want that for young girls to idolize.”

However, she is grateful she received help.

“But if I hadn’t gone into treatment,” she continues, “I don’t know if, one, I’d even be sitting here today, [or] two, if I’d be alive today.”

Outspoken actor Zach Galifianakis has dissed Ke$ha, reports Canoe Jam.

Galifianakis says he has constantly denied Ke$ha’s requests for dates, and flat out bashed her music upon meeting the singer.

Ke$ha has previously stated that Galifianakis is her ideal man, admitting she has the hots for fat and bearded men, but Galifinakis apparently doesn’t have the same penchant for sleazy blonde popstars.

“I saw that Ke$ha woman the other day. She was sitting by herself, and I walked up to her and said, ‘Listen, I got your e-mail. Your music is really bad! I don’t know who listens to it, but I imagine it’s, like, six year olds – and it’s a bad message,’” he tells Rolling Stone Magazine.

This isn’t the first time the ‘Hangover’ star has publicly dissed a celebrity. Just recently, he took aim at actress January Jones, calling her “rude” and stating she is an actress “everybody’s going to forget about… in a few years”.

I love his outspoken nature! It’s not often celebrities are so open. I can’t say I blame him for denying a date with Ke$ha, I can only imagine how classy that evening would be.
