OMG! Heidi Montag Undergoes Extreme Plastic Surgery Makeover

Heidi Montag. You have to admit, the girl is gutsy. And apparently addicted to plastic surgery as the headline of People magazine's newest issue on sale now, reveals.

Yes, both photos are of Heidi Montag. Before, left, and the new Heidi, right, in 2010. Heidi seems almost unrecognizable after an admitted 10 plastic surgery procedures in one day! OMG!

So, what's different about the celebrity? Bigger breasts, bigger lips, smaller chin, smaller nose, and apparently some other things like---mini brow lift, Botox in the forehead, fat injections in the cheeks, neck liposuction, ears pinned back, liposuction on her waist and thighs and a buttocks augmentation.

The Hills star is only 23, and yet has been slowly putting together a more beautiful beauty strategy for quite some time now. "For the past three years, I've thought about what to have done," the reality star tells PEOPLE. "I'm beyond obsessed."

We always thought Heidi Montag was pretty, and even prettier after her first nose job, done around 2007. Then she went for too ample a breast enhancement, and it's never stopped. But, we have to imagine, it's tough out there for any young woman growing up in such a beauty and youth-obsessed society. There is so much pressure on girls to be super skinny and look 'perfect.' And Heidi told People, that she was teased as a young girl about her looks, and the teasing didn't stop, even when she moved to L.A. and got a lucky television break:

"People said I had a] Jay Leno chin," she tells the mag. "And when I watched myself on 'The Hills,' my ears would be sticking out like Dumbo! I just wanted to feel confident and look in the mirror and be like, 'Whoa! That's me!' I was an ugly duckling before."

There's a lot of competition in Hollywood, especially in the pop star world, where Heidi so wants to be at the moment:

"I'm competing against the Britney Spearses of the world - and when she was in her prime, it was her sex appeal that sold. Obviously, looks matter, it's a superficial industry," Heidi explains.

So, how does Heidi Montag like the 10-round plastic surgery results? Well, we could only share the cover photo of People, for now, but Heidi is definitely pleased:

"I look way better and I'm way happier...my eyebrow lift just took my face to another level, made it a little bit more European-exotic," Heidi says. "And for the first time, I have sexy ears!"

By the way....Heidi's debut CD Superficial, drops tomorrow, and the lead single is called, Fanatic.

Hmmm. Words to chew on for a while.
