Chris Pratt has spent time in a Children's Hospital in Seattle.
The 37-year-old actor took to Instagram on Tuesday (11.10.16) to share the pictures he took with patients at Seattle's Children's Hospital, along with some touching messages about the people he met.
Alongside a photo of himself with a young girl battling cancer, the 'Jurassic World' star wrote: "Madisen is #strongagainstcancer. What an awesome kid with such a beautiful smile. She's a lover of art and fashion and she's going places. Thank you @seattlechildrens for the opportunity to come by and brighten some days. My heart is full. Proverbs 3:27 Don't withhold good from those to whom it is due, when it is in the power of your hand to do it. (sic)"
The 'Guardians of the Galaxy' actor also met a boy named Rowan, who dressed up as Groot from the hit movie for Halloween last year, along with his brother.
He wrote: "Rowan was Groot for Halloween and his brother was Rocket. What an awesome kid. Great parents and from a great family. You're in my prayers tonight little man. Stay #strong @seattlechildrens (sic)"
And Chris - who's four-year-old son Jack was born prematurely - made a special visit to the hospital's neo-natal intensive care unit, who specialise in caring for ill or premature newborn infants.
A picture of the star with two prematurely born infants and their mother was captioned: "Ever since Jack's premature birth, we have a special affinity for the NICU (neo-natal intensive care unit) Today I spent a little time with Coen and Zion, twins who were born too early only a pound and a half each. Thank you to the doctors and nurses at @seattlechildrens The boys are doing fine. Although they're both missing their big sis. (sic)"
