Derek Hough wants to remember all the steps of Hayley Erbert‘s pregnancy journey. 

Two months after the couple announced that they were expecting their first child together, the Dancing With the Stars judge showed off his wife of two years’ growing baby bump in a heart-melting video. 

In the clip posted to Instagram Sept. 15, Hayley, 30, walked through a field of grass at golden hour while rocking a gorgeous Champagne-colored slip dress and heels. At one point, she stopped and turned to face the camera while cupping her pregnancy belly. And in a second video, she struck a similar pose while donning a jaw-dropping red midi dress before wrapping her arms around Derek, 40, to smile for a selfie. 

Captioning the sweet footage, Derek wrote, “That’s my babie’S.” 

Back in July, the pair—who tied the knot in 2023 following eight years of dating—revealed that they were gearing up to welcome a new addition to their family. 

“We can’t believe the biggest thing to happen to us,” Hayley wrote alongside an Instagram Reel that showed their baby’s sonogram, “could be so small.”
