It didn't take Christina Aguilera much time to lose those pregnancy pounds!
On Sunday, less than three months after giving birth to daughter Summer Rain, the 33-year-old mother of two showed off her incredible post-baby body in a plunging red Rubin Singer dress. Attending the Breakthrough Prize Awards Sunday in Mountain View, Calif., with fiancé Matt Rutler by her side, Christina looked teeny tiny in her sexy gown, which perfectly accentuated her svelte, trim figure.
So how on earth does this hot mama, who also has a 6-year-old son, Max Bratman, with ex-hubby Jordan Bratman, look this great so soon after welcoming baby No. 2?! A source tells E! News the singer "was very healthy throughout her pregnancy and is continuing it now after the baby."
