Chris Pratt has contracted a lung infection after the births of three of his children because of a celebratory ritual with father-in-law Arnold Schwarzenegger

Speaking to guest host Claudia Winkleman on 'The Graham Norton Show', he said: "[Arnold] is a big cigar smoker - he's always smoking one on set, in his car, and in my living room.

"When we have a baby, he shows up with a Cuban cigar. I have asthma so I should not ever smoke cigars, but I do because I feel pressure from Arnold Schwarzenegger.

"So, every time I have a child, I have a cigar and about a week later I have a lung infection. It's a nice little ritual we have."

The 45-year-old actor can next be seen in 'The Electric State' but admitted it was only due to Katherine's intervention that he took on the project because he was ready for a break.

He said: "It is epic with truly stunning imagery.

"I had wanted to turn it down because I'd just finished a busy season of work and had been away for a while.

"We have four kids, so I wanted to take an extended period off but when my wife read the script, she said I had to do it. She either really loves me or she actually just wanted me out of the house again."

Chris recently spoke about his baby son and explained the youngster is "really chill".

Speaking on 'Jimmy Kimmel Live!', he said: "He's a really, really chill baby.

"He's sleeping. I sleep through the whole night but Mama's breastfeeding so she's up every couple of hours but he is really chilled

"He's not colicky or anything, he's not super loud. He's got this look on his face at all times that I just call resting bewilderment face.

"He's like this. Like everything he sees, he's like, 'Yes, this is great!' He's great. He just gets so excited to communicate."
