Miranda Kerr flaunts bikini body for Victoria's Secret less than four months after giving birth

Mirand Kerr (l. in Sept. 2010, r. on Sunday) welcomed son Flynn with Orlando Bloom on Jan. 6.

Less than four months after giving birth, supermodel Miranda Kerr is back to rocking her admirably svelte bod.

The new mom, who welcomed son Flynn with husband Orlando Bloom on Jan. 6, was photographed working during a Victoria's Secret shoot in Malibu on Sunday, clad in a skimpy black bikini.

Kerr, 27, has walked the runway in some of the company's sexiest lingerie as part of their annual Victoria's Secret Fashion Show, but sat out last fall due to her pregnancy.

She returned to the catwalk in early March, making a surprise appearance at a Balenciaga show during Paris Fashion Week. But Kerr's outfit – a long black dress – kept her post-baby body covered.

Kerr showed off her baby bump while posing nude for W magazine's December issue.

The model recently attributed her slim down to eating healthy foods as well as doing yoga and breastfeeding.

But there's some body changes that came with her pregnancy that Kerr has appreciated.

"My hips are bigger and my breasts are bigger," she told E! News last month. "I'm loving it. I feel more like a woman."
