'Princess' Christina Aguilera Hogs The Spotlight In Fishnets And Tiara

NBC

The focus was on Christina Aguilera on Monday's edition of The Voice, as the What A Girl Wants singer's larger-than-life personality, and attire, pretty much overshadowed the critical semifinals between the remaining eight crooners in the NBC competition.

Xtina didn't dress down, wearing a sparkly princess tiara and black blazer that revealed cleavage on top; and fishnets and knee-high leather boots below, showing off plenty of gams.

And she absolutely queened over former Mickey Mouse Club co-star Tony Lucca, who's being mentored by Adam Levine this season.

After one of his performances, she told Tony he did a nice job -- before implying Adam boot him in favor of someone else!

"I know the obvious choice is Tony," she said, "but [Adam] should take a look at Katrina Parker, because she's a star."

The Voice airs on NBC Mondays at 8/7c and Tuesdays at 9/8c.
