Miranda Kerr, together with her baby boy Flynn, graced the cover of Australian magazine Who's special issue.

For the second time, the Australian supermodel topped 2012's Most Beautiful People list of the magazine.

The secret of Miranda Kerr's beaming beauty?
It's in her adorable son, said the 28-year-old Victoria's Secret angel.
"I was working 18-hour days. Now that pace has slowed so I can spend the majority of my time with Flynn," Kerr told the magazine.
"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."

Flynn was born in January 2011 between Kerr and Orlando Bloom.
"I’m first a wife and a mother, and then comes work."

"Flynn is a natural in front of the camera, just like his mum!" according to Chris Colls, the photographer who shot the cover photo.

Among the 40 beautiful people featured on the list, 17 are Australians.
