“And just like that…our little guy is seven,” she posted on social media. “Happy birthday to the light of our lives. Nothing makes us smile more than seeing you smile. Daddy and I love you so much, Duke,” she gushed.

Fans and followers flooded the comments section with well wishes for the adorable boy on his birthday. Some even brought back memories from the episode of the couple’s then-reality TV programme, which showed their son’s arrival into the world.

Duke is Giuliana and Bill Rancic’s only son and was born via surrogacy in 2012.
