From gracing countless ads as a Victoria's Secret Angel to calling Pirates of the Caribbean heartthrob Orlando Bloom her husband, some might say that Miranda Kerr has accomplished some pretty enviable things in her life.

But at the CFDA Fashion Awards in NYC Monday night, the supermodel told Us Weekly that her greatest life-changing moment was having her son, Flynn. "He's the best thing I've ever done!" she gushed.

Clad in a black, two-piece Michael Kors dress, the 5-foot-9 beauty continued to rave about her son's milestones. "He turned five months old today, and it's such a fun age. He's smiling. He has two little teeth on the bottom now, so that's been a little painful."

Kerr, 28, gave birth to Flynn back in January, who weighed in at 9-pounds, 12 ounces. He's the first child for both Kerr and Bloom, 34. But despite giving birth to such "a very healthy and big baby boy," Kerr attributed her quick weight-loss to breastfeeding. "He's a hungry little boy," she told Us back in April.
