The couple first gave a hint in the musician’s new music video for ‘Wild’, which was released on Thursday.
At the end of the video, the cook book author could be seen rubbing her baby bump while being held by her husband as they stand together in front of the water.
Taking to her Instagram page, the singer’s wife confirmed the news as she showed off her growing baby bump.
