Chrissy Teigen pregnant with third child as she and John Legend announce baby news in Wild music video

Chrissy Teigen and husband John Legend are expecting their third child, the couple has announced.

The loved-up pair revealed the happy news in the music video for Legend’s latest single Wild.

In the video, the US singer, 41, and his model-turned-presenter wife, 34, are seen messing about on the beach in Mexico, driving in a convertible and generally looking blissfully loved-up.

Towards the end of the three-minute clip the couple are joined by their two children, Luna, four, and two-year-old Miles.

Then, wrapped in her husband’s arms, Teigen places her hand tenderly on her stomach – in a sign of the “beautiful surprise” to come.

As she shared a teaser for the video on Twitter, Teigen posted a single emoji of a smiley face surrounded by hearts.

Teigen then shared a mirror selfie in which she's showing off her bump on Twitter.

Plenty of famous faces soon shared congratulatory messages for the couple, with Frozen star Josh Gad commenting "CONGRATS!!!!!!!" on Teigen's Instagram.

Commenting on a still from the video posted on Legend's Instagram, actress and model Brooklyn Decker said: "It's absolutely magic."

The couple wed in 2013 after first meeting on the set of Legend's Stereo music video in 2006.

In a sweet touch, the Wild video was directed by Nabil Elderkin, who directed the pair on the Stereo set 14 years ago.

Teigen isn't the first star to announce that she's expecting via a music video.

Earlier this year, Katy Perry revealed that she's pregnant with her first child by displaying her blossoming bump in her Never Worn White video.

The singer and her fiance Orlando Bloom will welcome the baby, their first together, in the coming month.
