Katy Perry may have started a trend by revealing her pregnancy in a music video.

Perry announced her impending motherhood in the video for 'Never Worn White' a few months ago, and now her fellow musician John Legend has revealed similar news.

The video for 'Wild' shows Legend and his wife Chrissy Teigen in various states of undress as they participate in PDAs and frolic on a beach.

At the end, the camera pans back to reveal Teigen cradling what appears to be a baby bump.

The news has been confirmed by Teigen on Twitter:

The pair are already parents to Luna (4) and Miles (2).
