“Surf school in session!!” The Apprentice alum, 45, captioned the image practicing his surf moves with his preschooler.
The proud papa and his wife, Fashion Police star Giuliana Rancic, posted more photos from their Spring Break vacation.
The reality star, 42, recently posted an inspirational message on her 5-year anniversary of being cancer-free.
Prior to welcoming Duke, Giuliana went through three rounds of IVF treatments before finding out she had breast cancer. The couple put their plans to start a family on hold while Giuliana underwent a double mastectomy.
After beating cancer, the Rancics turned to a surrogate who would later deliver Duke. Unfortunately, the same gestational carrier miscarried their last remaining embryo.
