Breastfeeding seems to be doing wonders for new mom Miranda Kerr – she posted a photo of herself nursing 3-month-old son Flynn while at a shoot for Victoria s Secret on Thursday.
The Australia beauty looked camera-ready while lounging backstage in a silky robe, red stilettos and wavy hair.
“Another day in the office. Back to work for VS. Flynn is with me on set! Lil cutie pie Xxx, Kerr, 28, Tweeted.

“It’s genetics, he said on The Ellen DeGeneres Show on Friday. “It’s amazing. She looks incredible.
When DeGeneres asked how she got back into shape so quickly, Bloom, 34, responded, “A lot of breastfeeding.”
