NEW YORK — Christina Aguilera recently debuted her slimmed-down body, but the singer says she doesn't work out like crazy.

The 32-year-old is on the cover of Maxim magazine's October issue. She's sporting a bra and a big shirt in the cover photo and a fitted dress in the magazine spread.

In a phone interview Thursday, Aguilera says her daily routine includes working out – on some days.

Says Aguilera: "If I can squeeze in a workout, great. If not, that's OK, too."

The Grammy winner adds that her 5-year-old son, Max, is also keeping her in shape: "Running around with him all day is pretty good exercise."

Aguilera will return to the fifth season of NBC's "The Voice" on Sept. 23.
