Miranda Kerr and Orlando Bloom showed off their newborn son, Flynn, on the Victoria's Secret supermodel's blog Tuesday.

Under a post titled "Our darling little man xxx," Kerr shared that Flynn arrived Jan. 6 and weighed 9 pounds, 12 ounces. The post was accompanied by a photo taken by Bloom of Kerr nursing.

Orlando Bloom and Miranda Kerr tie the knot

"I gave birth to him naturally; without any pain medication and it was a long, arduous and difficult labour, but Orlando was with me the whole time supporting and guiding me through it," Kerr wrote. "I could not have done it without him. We are so happy and are enjoying our time together as a family. He is our little ray of sunshine."
