The young star was interviewed for the October issue of the magazine, which hits newsstands this week.
The singer said that she wants to keep certain aspects of her life to herself, saying, "My marriage is sacred to me, and I feel that they (the media) would exploit it."
Aguilera reveals in the interview that she is interested in acting, although she turned down an offer to star in her own reality series. Aguilera added, "I think so many people who start off as musicians and cross over just end up playing themselves. To me, that’s not a challenge whatsoever."
