Miranda Kerr, Orlando Bloom welcome son, post a nursing picture

It's (officially) a boy for Miranda Kerr and hubby Orlando Bloom.

The couple welcomed baby Flynn on January 6, as confirmed by a post on Kerr's KORA Organics website.

"I gave birth to him naturally without any pain medication," the supermodel brags blogs. "It was a long and difficult labor, but Orlando was with me the whole time supporting and guiding me through it. I could not have done it without him."

With Flynn weighing in at 9 lb 12 ounces -- yeah, that sounds rough.

"We are so happy and are enjoying our time together as a family," Kerr adds. "He is our little ray of sunshine."

She also posted a breast feeding picture taken by the new daddy.

Congratulations to the happy family!
