The stunning mom-to-be shared the news in a series of maternity photos that she uploaded to Instagram.
Shepard also reposted the second of the three images, captioning much more simply, "My baby is making my baby!" Since it's Mother's Day, you couldn't pick a better day to announce your pregnancy, so that's what Chanel Iman did.
One photo particularly shows Shepard planting a kiss on Iman's belly.
The couple shared photos from a photo shoot of two of them topless, wearing matching jeans and Calvin Klein underwear, taken by photographer James Macari.
"Our fairytale continues as we wait for the birth of our baby", the 27-year-old Victoria's Secret model exclusively told PEOPLE after posting the announcement online. "I can't wait to share it with our little one". They met at Victor Cruz's birthday party in November 2016. She and her groom tied the knot just four months after their dreamy engagement in Beverly Hills.
Mother's Day had a very special meaning for model Chanel Iman who is expecting her first child with football star Sterling Shepard. Their A-list guest list included Chrissy Teigen, Gabrielle Union, Tiffany Haddish and Odell Beckham Jr.
