Looking good, Christina Aguilera

The 34-year-old beauty performed at the Vanity Fair after-party last night following the 2015 Oscars, where the blond beauty stunned in a fitted white gown that highlighted her enviable curves. 

With fiancé Matthew Rutler by her side, the X Factor judge turned heads in the form-fitting dress that featured both a high neckline and a crackle-style pattern, which she paired with sky-high sparkly Christian Louboutin peep-toe pumps. Aguilera added embellished silver hoop earrings and number of matching rings to her ensemble while wearing her hair in a fierce, high ponytail.

While it's been only six months since the singer gave birth to her second child—daughter Summer Rain—Aguilera's post-baby bod has been on point since she first stepped out and debuted her figure just two weeks after welcoming her wee one

"She is very dedicated to yoga," a source told us at the time. "So much that she has never stopped practicing it. She did yoga the entire time she was pregnant. And Christina has already been working hard on getting her bod back in shape! She is doing private yoga sessions and loves how it makes her feel."

The source added that Christina is "obsessed" with yoga, but also maintains her figure by "eating clean and watching her portions."

Earlier this month, the mother of two, who is also mom to son Max from her first marriage to Jordan Bratman, shared the first photo of her sweet baby girl and opened up about raising her daughter. 

"She was literally like an angel…We had an immediate calm bond, and I felt unexplainably connected to her and her spirit," the blond stunner told People after giving birth

Aguilera added of her two kids, "They are the center of my universe." 

Too sweet!
