Does Carrie Underwood's stunning beauty and toned physique make your mind go blank and leave you weak in the knees? If so, you're not alone. According to GuySpeed, many people are 'suffering' from the same symptoms, which is why they named the country music superstar one of the most mind-numbingly hot women of 2012.

The 'Blown Away' singer lands at No. 30 on the first-annual countdown, blowing away a bevy of beautiful ladies as one of the fairest women in all the land. Though Underwood is now as physically perfect as humanly possible, the singer admits she wasn't blessed with a naturally flawless complexion.

“If I could go back and talk to my 15-year-old self I’d be like, ‘Seriously, listen to your mom,’” says the Olay beauty products spokesperson. “Drink more water, put more sunscreen on, moisturize. There are a lot of people like me who wish they did more.”

Underwood has become the fresh face of Olay's Beauty by Example charitable campaign, which has joined forces with the Looks Good, Feels Good organization. Women are encouraged to visit Olay’s Facebook page and sign a declaration saying that their mom is beautiful, both inside and outside. Olay will then donate some of their product to the goodwill organization, which helps boost the self esteem of women who are being treated for cancer.

Underwood is currently gearing up for the premiere of her highly-anticipated 'Blown Away' music video, which will debut tonight (July 3o) on 'E! News' and E! Online. The track is the second radio single from her recent chart-topping album of the same name.
