Chris Pratt and Anna Faris' son is doing just fine after spending a month in ICU.
The Parks and Recreation actor hit the Late Show with David Letterman to dish on his son, Jack, telling Dave Wednesday that the couple's 4-month-old baby is "totally healthy now."
What Chris Pratt really likes about wife Anna Faris' body
"Oh, God, he is just..he's amazing," the 33-year-old doting dad said. "I love him so much. He's just a ball of joy. He's terrific."
"He was born nine weeks premature, so we spent a month in the intensive care unit with him. But he's totally healthy now. He is just so perfect and I love him so much."
Faris and Pratt welcomed their baby boy in August, after tying the knot in 2009.
