Miranda Kerr & Flynn Cover 'Who' Most Beautiful Issue

Miranda Kerr graces the cover of Who‘s “Most Beautiful People 2012″ issue with her 15-month-old son Flynn.

“I was working 18-hour days. Now that pace has slowed so I can spend the majority of my time with Flynn. I’m first a wife and a mother, and then comes work,” the 28-year-old model told the Australian magazine.

Flynn, Miranda added, is “like a little ball of sunshine. He’s a really charming, lovely boy. He has that look in his eye like, ‘What trouble am I going to get into next?’ But I like that, it’s like me.”

The mag’s special family portrait package also features Liam Hemsworth and his older brother Chris!
