Adriana Lima made quite the post-baby debut Wednesday night, taking to the catwalk for the 2012 Victorias Secret Fashion Show in lacy red lingerie less than two months after giving birth to her second child. Any sign of that baby bump had already disappeared.

Of course, it didnt exactly happen overnight (though it may seem that way). Bringing to mind that old adage that pain is beauty, the Victorias Secret Angel has been tweeting about her weight loss for weeks, posting pictures of herself in sweaty workout clothes and showing off cuts she incurred while boxing.

Tired ... Very very tired, she tweeted last month.

Even without the added baby weight, getting in shape for one of the biggest lingerie events in the world isnt easy.

It is really intense, its not really the amount of time you spend working out, its the intensity: I jump rope, I do boxing, I lift weights, but I get bored doing that, she told The Telegraph in 2011. If I am not moving I get bored very easily.

Though Lima made an astonishingly swift! comeback, the 31-year-old didnt make the quickest return to the catwalk in Victorias Secret Angel history. That honor goes to 36-year-old Heidi Klum, who strutted down the runway in a purple corset in 2009, just five weeks after giving birth to her fourth child.

I think Im partially lucky, Klum told the New York Daily News in 2009. I eat very healthy, I do watch what I eat a lot. People always think, Oh, she probably doesnt eat anything. I do eat a lot, but I do watch what I eat. I try to stay away from the carbs.

While Klum modeled an admittedly more demure creation (at least by Victorias Secrets standards), not everyone was pleased with the supermodel's decision in the wake of her pregnancy. Though people commented online that Klum looked great, many felt it was just too soon for her to join the other Angels.
