The Victoria's Secret model spilled the beans in the September issue of Spanish Vogue.
"Yes, I'm pregnant. Four months along," Kerr, 27, told the mag.
Kerr wed 33-year-old actor Orlando Bloom in July in a quiet ceremony that surprised many close to the couple.
"It was exactly what we both hoped for and it turned out as planned in every way," Kerr gushed to an Australian newspaper. "We always intended for the wedding to be a private and intimate occasion and we haven't shared any details as it is something we'd like to keep as our special secret."
Miranda, 27, isn't planning on slowing down after the baby is born, but rather hopes to take a cue from her fellow supermodel moms.
"I've always been open about wanting to be a mother one day, and I've always thought Orlando would be a great dad," Kerr said. "I think having children and pregnancy is a part of life. I look at how models like Heidi Klum, Adriana Lima and Alessandra Ambrosio have done it and made it a part of their lives."
Congrats to the happy couple!
