The singer and his baby boy posed for the adorable photo while both wearing Buzz Lightyear costumes - and while surrounded by Buzz Lightyear toys.
While Tom is wearing a T-shirt version, seven-month-old Buzz is sporting the full getup and is clutching his very own little toy Buzz.
Sandwiched in between the pair is a large cuddly toy Buzz and a smaller plastic version of the Disney character. Too cute!
Buzz's TOWIE star uncle Mario Falcone shared the snap with his followers on Twitter, saying: "Best picture ever! The bro in law @tomfletcher and little Buzz!"
Tom, who found fame in pop band McFly, welcomed Buzz into the world with his wife Giovanna in March, however they both insist he has not been named after the character.
Speaking on Lorraine in May, Giovanna said: "We liked the name for a few years, but actually we went off it when I was pregnant.
"Then in the last month, it came back on the table. I know everyone thinks we named him after Buzz Lightyear but we haven't."
Well even if he wasn't named after Buzz Lightyear, little Buzz is definitely set for infinity and beyond!
