Wonder Girls' Sun recently gave birth to daughter, Hailey, and uploaded pictures of the baby's adorable and super tiny feet and hands.  Now, the new mother revealed pictures of herself with her baby.

She tweeted, "The mystery of natural birth.  My super quickly recovering body... :-) Never feeling tired but just joyful in peace."

She uploaded a four-set collage of herself looking beautiful as usual like she did not just recently undergo an eight-hour labor period.  Meanwhile in the pictures, baby Hailey is peacefully sleeping against her mother's chest.
