"Thank you all so much for your prayers for us as it hasn't been an easy journey," Katherine continued. "We thank God everyday for this wonderful blessing and can't wait to share this journey with all of you!!"

The 26-year-old model and 25-year-old NFL star began dating in 2012 and wed in 2014.

Interestingly enough, the couple keeping their pregnancy a secret for four months means that a "fake" pregnancy announcement that Katherine made in October was actually kind of real!

"Guess whatttt??? I am so excited to announce that I am 20 minutes preggers with an Egg Mcmuffin," she joked at the time.
