Christina Aguilera Looks Radiant in Red 3 Months After Giving Birth

Christina Aguilera stepped out on Sunday showing off her slim post-baby body!

The 33-year-old attended the Breakthrough Prize Awards Ceremony just three months after giving birth to daughter Summer Rain.

She looked radiant in a red plunging dress that accentuated her curves and shape in all the right places. Christina, who was accompanied by fiance Matt Rutler, reportedly owes her post baby-body to healthy living.

“She is very dedicated to yoga. So much that she has never stopped practicing it. She did yoga the entire time she was pregnant,” a source told E! News. “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. [She] loves the way it makes her look and feel, inside and out. It’s so calming and keeps her centered. She is obsessed!”

The singer’s son Max Liron, 6, also keeps her moving and on her feet.

“Everything is about moderation,” the source continued. “She will have cheat meals occasionally too. Running after Max also is helping her burn some extra calories. There’s never a quiet moment, Max is very active!”
