Saturday night’s Kids’ Choice Awards proved to be another x-cellent moment for Xtina.

Hitting the stage with Pitbull to sing their new single “Feel This Moment,” Aguilera, 32, once again flaunted her slimmed-down figure.

Unlike the black LBD she sported at the season 4 premiere of The Voice last week, Aguilera opted for a decidedly more kid-friendly black pantsuit (complete with suspenders, no less) for the high-energy performance.

“It’s amazing what having some personal time can do, not only for the body, but also for the mind and the spirit,” a source told PEOPLE of her fitter physique. “She has been trying new types of foods and exploring new methods of exercise – not for diet or weight, but more for her mind and well-being and overall sense of good health.”
