This is lovely news given how Chrissy have been very open regarding their issues with conceiving. To quote the model "It's finally happening."

Teigan shared the news via her Instagram last night, with the below picture captioned: "John and I are so happy to announce that we are pregnant :) As many of you know, we've been trying to have a baby for a while now. It hasn't been easy, but we kept trying because we can't wait to bring our first child into the world and grow our family. We're so excited that it's finally happening. Thank you for all your love and well wishes. I look forward to all the belly touching! Xx" Yeeeeeaaaah - you say that now...

The 29-year-old had said in a previous interview: "The 29-year-old model recently spoke out about how she and the musician have wanted children. “I would say, honestly, [that] John and I were having trouble. We would have had kids five, six years ago if it had happened, but my gosh, it’s been a process."

Congrats and enjoy every minute!
