The birthday boy shared few shots from the party on Instagram and thanked his wife and friends for the surprise.
"Best. Birthday. Everrrrr. Courtesy of my wife, buddy, and international spy, @blakelively. With huge thanks to my favourite restaurant in NYC and a special shout out to our children for not ruining everything like they planned," he wrote.
