The 44-year-old Better Homes and Gardens host’s 21-year-old son, Joe is expecting a baby with his girlfriend – and now Johanna has shared the first picture of the baby bump.
Johanna took the photo of Joe's partner Katie Buttel lifting up her shirt to reveal her stomach, while her son kneeled down next to her smiling.
'Got to feel my grandson kick for the first time tonight,' Johanna wrote in the caption. 'It was so awesome. Katie is looking so beautiful, and everyone is so excited. Bring on 2018.'
Johanna was previously married to actor Gary Sweet before a messy split when she was only 24.
The former House Rules host is now married to builder Todd Huggins.
