    Christina Aguilera is debuting her post-baby body!

    The 33-year-old singer, who gave birth to new daughter Summer Rain just over two weeks ago, reunited with her ex-hubby Jordan Bratman earlier this week for a back to school picnic with their son, Max, in Santa Monica.

    In the first pics of Aguilera post-pregnancy, the mother of two looked positively glowing in a dark maxi dress, a black jacket and sandals with sunglasses and a straw fedora. The Voice coach was all smiles while sipping a coffee as she enjoyed the day with Max, his father and Bratman's mom. Both parents appeared happy while supporting their 6-year-old.

    "They seemed really cool with one another," an onlooker says of the exes, who spent about two hours hanging out with other kids and their parents during the picnic. "[Christina] was very friendly with anyone who came up to her. She interacted with all the kids and parents. She was glowing, she looked really happy."

    When the picnic was over, Bratman walked Aguilera to her limo and they chatted for about 10 minutes. Bratman and Max hugged Aguilera goodbye and she left alone.

    Aguilera and her fiancé Matthew Rutler welcomed Summer Rain on Aug. 16 in L.A. Shortly after the birth, a source told E! News of the couple's unique name choice, "Christina wanted something different and unique for the baby's name. She loves how Summer Rain Rutler flows together and thinks summer is an amazing time of the year. She has always been a more expressive person and a little bohemian who is inspired by words and daily life."
