Jason Sudeikis has defended Olivia Wilde's breastfeeding photo.
The 'Horrible Bosses' star - who has a six-month-old son, Otis, with his 30-year-old fiancee - has admitted he approved of her decision to be photographed feeding Otis during a shoot for Glamour magazine in September and thinks the picture is "great".
He told Access Hollywood: "That was great. That's a working mom. "[It was] not planned. He was there, and he did a little pop in visit to see mom and duty called."
The 39-year-old actor was more shocked by the fact his baby son relieved himself over a designer gown during the shoot and joked the tot must have been trying to create his own masterpiece in the style of graffiti artist Banksy.
He said: "He peed on a very expensive dress. He's Bansky. People don't know my son's Banksy."
Jason also confessed he felt changed by fatherhood and finally understands why his 'Horrible Bosses' co-star Charlie Day was always keen to leave the set and get home to his family instead of go out and have drinks with his friends.
He explained: "I mean, as these guys well know, I remember a lot of times Charlie wanting to get home from set and saying, 'I've got to say goodnight to my boy,' and before [fatherhood] happens, you're just kind of like 'Come on, man, let's get a beer!'
"Now I'm like, 'Oh yeah, yeah I get that. Let's get home and say hi to the little guy. Tickle him a little bit, before he falls asleep'."
