...it was a seriously heartwarming moment.
You can see the sheer joy on his face in these photos.
In an interview with Huffington Post, Chelsie talked about how amazing Will's reaction was.
“He went from pure shock to being completely overjoyed with tears flowing,” Chelsie told HuffPost. “Throughout the whole shoot he just had the biggest grin on his face and kept repeating, ‘I just can’t believe it!’”
The photographer, who is a childhood friend of Chelsie's, talked about how much she loved being involved in such a wonderful moment.
“I was able to witness someone’s entire life changing right in front of me,” Kara said to HuffPost.
Chelsie went on to tell HuffPost about how much Will loves little ones.
“If you ask anyone that knows him, he is just amazing with kids,” she said. “If there is a baby around, 100 percent guaranteed it will take him .01 seconds to find it and ask if he can hold it, so I knew he would be more than thrilled once we were starting a family of our own.”
