Miranda Kerr, Flynn Cover 'Who' Magazine's Most Beautiful People 2012 Issue (PHOTOS)

It's pretty much common knowledge that Miranda Kerr is drop dead gorgeous and that her son, 15-month-old Flynn, is the cutest thing on two legs. (Seriously, we've got proof.)

But Who magazine, Australia's version of People, has made it official by putting the mommy-son pair on the cover of its "Most Beautiful People 2012" issue, out this week.

For the cover, which shows Miranda in black and Flynn in white and a beaded necklace, the pair posed for their first-ever photo shoot together.

Which isn't to say there haven't been plenty of photos taken of the Aussie model and her son. Miranda was seen toting Flynn (he's gotten so big!) out of yoga class in Hollywood yesterday (see below) and she and hubby Orlando Bloom (who is sadly absent from the Who cover) took Flynn for a hike on Orlando's birthday.

Although honestly, they could be doing anything and we swoon over this family's collective cuteness.
