Oh, Christina Aguilera. How we love you so for keeping us guessing when it comes to your wardrobe. The newly toned coach on The Voice has not only managed to maintain her slender figure, but she showed off several different styles this past season (and we loved almost all of them!). Whether she shunned pants, went for the demure schoolgirl look, or bared her cleavage in a sexy black bandage dress, Xtina looked amazing. And her fashion at Tuesday night’s Hollywood Stands Up To Cancer event was no exception.

The “Say Something” singer donned a casual yet chic look: a white blouse with black stripes tucked into black, shiny skinny jeans. With her neckline exposed, she managed the perfect measure of sultry in her ensemble. Of course, she didn’t deviate when it came to her signature sky-high, peep-toe, black Louboutins, dark red lipstick, long lashes, dark nail polish, bling, and a fedora. While she went sans extensions for most of the season on The Voice, she wore them last night for a look of long, romantic, blond curls.

One of her best accessories was her boyfriend, Matthew Rutler, with whom she showed up to the event, arm-in-arm — though they didn’t pose together on the carpet. Xtina’s main squeeze looks as though he might use the same stylist, as he donned a slick blue jacket with a grey V-neck tee and black skinny pants.

There was a rumor before this past season started that The Voice producers asked her to tone down her look, and she took it to heart. We love when the pop diva goes casual chic, and we think Christina’s look last night was perfection. Our only complaint? One of these days, we’d love to see her lose that faux tan and go au naturel.
