Chris Pratt and Anna Faris' son wrote a sweet note to his dad while filming

There is nothing more heartwarming than to see Chris Pratt keeping his kids close on set, even when things get a little gory. Chris posted a selfie showing off his abs and a fake bloody gash on his collarbone on July 18, captioning it "Lookin' cut" to show where he took the snapshot.

The actor previously revealed that he had already experienced the fake bloody gash during filming. The mirror selfie, which appeared to be snapped in the bedroom of his trailer on the set, has been noticed by eagle-eyed fans, who noticed a little Easter egg tucked away in the selfie.

There was a yellow Post-it note stuck to a wooden beam in Chris' room that read, "See you at 8:00 ish."

A heart symbol was engraved on it by Jack, his 9-year-old son with ex-wife Anna Faris.The account for Maria Shriver's Sunday Paper written, "The note from Jack [heart emoji]" seems to have captured the attention of even the Schwarzenegger family.

Patrick Schwarzenegger's sister Katherine Schwarzenegger, who is married to Chris, laughed at the note. The divorce of Chris and Anna was finalized in 2018, and Anna married cinematographer Michael Barrett soon thereafter.

Their daughters Lyla, 23 months, and Eloise, nearly 2 months, were born soon after Chris and Katherine tied the knot in 2019.

Our second daughter was born back in May, and the couple commented, "We are very excited to announce it. Mom and baby are doing well. We are grateful beyond words."

As Chris told Life From E!, "I'll follow her lead because she just really knows what she needs to do." He then gushed about Katherine's unique maternal instincts while walking the red carpet at the Los Angeles premiere of Jurassic World Dominion.  

In addition, he revealed big changes to his diet since becoming a father of three. My current diet consists mostly of pizza and everything my children eat off their plates. 

I cook lunch for them and they take home only half and think 'Well, it doesn't count if it was on their plate."My children eat a lot of chicken nuggets, fries, and tater tots."
