Christina Aguilera wowed fans when she debuted a hot new look earlier this month on The Voice.

The singer, 31, traded her skin-revealing, low-cut dresses and bright crimson lipstick for more flattering designs and makeup to match.

And in keeping with her makeover, Aguilera wore another chic outfit on Tuesday's episode.

"You can never go wrong with a little black dress," she wrote on her website of the black-and-blue Alexander Wang sweater dress. "And I loved this look as we added a pop of color."

Makeup artist Jake Bailey amped up the ensemble with vibrant blue eye makeup, major lashes and berry-colored gloss.

"She wanted something fun and what's more fun than electric blue liner and giant lashes?" he said on the site.

On Monday night's episode, Xtina wore a purple printed Alexander McQueen dress, studded Christian Louboutin heels and Loree Rodkin earrings.

"I wanted to play a little with color and print," stylist Simone Harouche said of the look. "Christina loves color and looks amazing in it!"
