Watch Christina Aguilera's First Live Performance In Awhile

Christina Aguilera hath returned.

In her first live performance since the birth of her baby girl, Summer Rain, Xtina graced our ears with her screaming rendition of “Beautiful” at the The Breakthrough Prizes for math and science at NASA with Vanity Fair and French Laundry Ames Research Center on Sunday.

Her singing was… out of this world.

Watch and listen:

Love her!
