Christina Aguilera Graces the Cover of Maxim: 'Sexiness Should be Effortless'

Christina Aguilera graces the cover of the October issue of Maxim magazine, and she looks sexier than ever! The 32-year-old star posed wearing a black push-up bra and a white men's button-down-shirt, Voxxi reported.

In talks with Maxim, the "Your Body" singer opened up about her definition of sexy, what she likes in a man and who her favorite co-star from the Mickey Mouse days was.

"I'm such a down-to-earth girl, I'm comfortable in just a jersey and boy's underwear. Trying too hard to be sexy is the worst thing you can do," said Aguilera. "Sexiness should be effortless," she added.

The singer also talked about what turns her on. "The quickest way for me to feel weird and run for the hills is if somebody sits down and serenades me with a guitar. It's not my thing," said "The Voice" judge.

Aguilera explained she likes "genuine guys" and that's why she likes to stay away from celebrities. "I don't care about money, because, trust me, I can support myself."

Maxim asked her which one of her co-stars on the Mickey Mouse Club was cooler - Ryan Gosling or Justin Timberlake? "They were both very charismatic, but I think I have to shy away from the question," said the singer. "I don't want this to bite me in the butt later. They were tight, you know. They'd walk around together all the time, same as me and Britney would. Now look at us. It's funny how that played out."

Back in July, Aguilera showed off her amazing new body by donning a tiny pink dress on the red carpet of the NBC press event for the upcoming season of "The Voice," where she is set to return as one of the coaches in the competition.

The singer has reportedly lost over 15 pounds in the last couple of months, thanks to a strict workout regime and a very healthy diet. She has also taken a few months off from work and has reportedly used the time to focus on herself and improving her body.

According to People Magazine, Aguilera has been focusing on intense exercise regimes with personal trainer Tee Sorge and has also had a drastic change in her dietary regime, trying to stay clear of burgers and other greasy foods in exchange for a seared tuna salad or sushi at her favorite L.A. restaurant, Hillstone.

A second source added that the singer has always been a confident person no matter what her weight is at the moment, saying that the superstar will always be comfortable in her own skin.
