X-tina is the Maxim magazine, cover girl wearing a pair of white panties, a black bra and white men’s shirt showing off her slimmed down figure.
"I’m such a down-to-earth girl, I’m comfortable in just a jersey and boy’s underwear," Christina says in the October issue of the magazine, looking sultry in the steamy picture.
"Trying too hard to be sexy is the worst thing you can do. Sexiness should be effortless," the Voice coach says.
The "Dirrty" singer, 32, has been dating Matt Rutler for three years and she said she’s the submissive one in their sex life.
"The only place I don't need to be in control is the bedroom.
"Sometimes being sexual with my partner is a great way to blow off steam at the end of a hard day's work. I'm not the girl who's going to be too tired."
