Looking rosy cheeked, trim and baring a flawlessly flat tummy, Miranda Kerr poses in a skimpy black bikini – just three months after giving birth
to son Flynn.
The Australian model rocked the two-piece by Have Faith during a photo shoot in Malibu, Calif., on Sunday.
It's hard to believe Kerr, who married
Flynn's dad, Orlando Bloom
, last July, gave birth on Jan. 6.
But the model's figure shouldn't be too shocking – Kerr, 27, gave us a taste of her progress a few weeks ago when she attended an event in Los Angeles wearing a figure-hugging
Hervé Léger by Max Azria zip front dress.
