It’s back to basics for pop diva Christina Aguilera.

The 32-year-old Voice coach swapped her typically colorful outfits for skimpy lingerie on the October 2013 cover of Maxim. The “Beautiful” singer shocked fans and critics alike when she debuted her slimmed-down physique a few weeks ago at the 2013 TCAs, the result of a new diet program and an amped-up workout routine.

Xtina has had ups and downs with weight, but the mother of 5-year-old Max finally seems to be comfortable in her own skin.

“Sexiness should be effortless,” she said in Maxim.

After divorcing hubby Jordan Bratman in 2010, she moved on to now-boyfriend Matthew Rutler and the two seem to be happier than ever.

The couple moved out of the home she used to share with Jordan and now lives in a Beverly Hills mansion.

Personal life aside, Christina took some time for herself during Season 4 of The Voice, but come fall is returning to her red throne.
