The Scrubs star shared a gorgeous picture of him and son Rocco enjoying a cute cuddle together.
In the fun snap, the pair pose cheek-to-cheek with Rocco's little face squished up next to his dad's.
Donald's wife CaCee Cobb captioned the photo, "Texas is for lovers." So sweet.
Back in October the couple announced on social media that they were expecting a second child together, sharing a picture of Rocco with the caption, "I'm a big brother!"
The expectant parents confirmed last month that their new arrival will be baby girl, though no due date has been revealed yet.
Speaking about his wife's second pregnancy, Donald said things were tougher for CaCee this time around. "That term, 'morning sickness,' is bulls**t. [It's] all day sick... I have nothing but respect for her," he said of his wife.
Donald has four other children aged between 13 and 17 - three from his marriage to Lisa Askey and one from a previous relationship.
