After giving birth to her son Flynn in January, Miranda Kerr didn't waste any time jumping head-first back into her career. Flynn wasn't even two months old before his model mama called a babysitter so that Kerr could make her first post-baby runway debut at theFall 2011 show in March. Kerr had worn a long, draped black frock on the catwalk that would have camouflaged any remnants of her baby bump, but it looks like whatever coverage the model might have needed a month ago is a thing of the past. This weekend, Kerr splashed around Malibu wearing nothing but an itty-bitty black bikini for a Victoria's Secret photoshoot, making it abundantly clear that she'd annihilated any post-baby bulge (photo below). In fact, the model is so absy that I'm beginning to doubt that she actually birthed a child less than three months ago – maybe it was all just a dream, or maybe the supermodel just hired a personal trainer and got really into oat bran.
