The picture, which shows a rosy-cheeked and smiling Kerr nursing her newborn son, was taken by proud father Orlando Bloom and appears with the caption "Our darling little man xxx."
Kerr also revealed a bit about her delivery. "He weighed 9lb 12 ounces (a very healthy and big baby boy)," she writes on the blog. "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. I could not have done it without him."
So far, so similar... to that other model mum, Gisele, who also had a natural labour and has been an outspoken proponent of breastfeeding. Now we just need to wait and see how soon it is until Miranda's back in front of the cameras.
