Frankly, we're surprised that the chief angel has still been walking the Victoria's Secret runway after all this time, considering her myriad other duties, including playing the the host of "Project Runway" and designing two new lines -- a maternity clothing collection and a fitness shoe. All of this is to say nothing of the fact that she's also become a mom four times over in the last decade. But then again, when you're 37 and look that good, why stop?
The lingering question of who will replace Klum as VS's "Head Angel," however, remains. Many of the top models in the brand's arsenal are either currently pregnant (Miranda Kerr and Doutzen Kroes) or just recently had a baby (Adriana Lima), though -- taking Klum as a prime example -- that doesn't necessarily mean they're ruled out. There are also some A-listers worth considering right now: veteran Alessandra Ambrosio, for one, or perhaps a rising star like Chanel Iman.
