The 28-year-old, who has a son with husband Orlando Bloom, has topped a list compiled by Australian magazine and celebrated the accolade by posing for the publication with her 15-month-old son, Femalefirst reported.
"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," she said.
The Victoria's Secret beauty said she sees a lot of herself in Flynn, particularly his naughty side. "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."
