"So the Mclean family will be expecting a new addition to the family next spring!!" he wrote alongside a photo of the same Air Jordan sneaker in four different sizes. "#laborday! Ha get it 'labor' day! I'm a goof!" he added. "#avaisgonnabeabigsister #baby2! Keep u all posted!! We're so excited."
The couple welcomed their first child, daughter Ava Jaymes in November 2012. In January, McLean, 38, told People that the 3-year-old was making it rather hard to for them to find time to focus on baby No. 2. He also revealed that they had considered adopting.
"Whatever our next child is, boy or girl, you would think that, 'Oh, I did it once, I've got it,'" he said. "No. It's hard. It'll make it easier, but it's still going to be a brand new learning process."
Best wishes to the happy couple!
