The "Deadpool" star quipped Wednesday night on "Conan" that he just wanted to get out of the house because having "two [children] under two is tough."
"Yeah, a lot of estrogen," Reynolds, 40, told host Conan O'Brien. "It’s like an American Girl doll took a s--- on my life."
Reynolds must've had a hunch he was in hot water, according to his wife of four years.
Lively, 29, shared on Instagram a photo of a cookie with the caption: "The ways I know that @vancityreynolds got himself into huge trouble on @teamcoco tonight: Not only did he come home with my true love, @levain_bakery cookies, but he personally toasted them for me and brought me a cup of milk WITH ICE. Literal brownie points."
This wasn't the first time Reynolds dropped hints about baby number two. He also said last month that the family's new addition was a baby girl.
"The mobile above my daughter’s crib is just a whole bunch of NuvaRings," he joked, referring to the birth control device. "So she remembers how lucky she is.”
The couple welcomed their second child in September, but have yet to reveal her name.
Their 4-weeks-old baby girl joins big sister James, 23 months.
