It's hard to believe that the super muscular and manly Jersey Shore men used to be innocent little children, but we have proof, y'all!

Ronnie Magro took to Instagram earlier today (April 25), posting one of the cutest Throwback Thursday pics to date. Along with a baby pic of himself wearing a diaper, crossing his arms, and rocking a birthday hat, Ronnie wrote, "#WhatsUpHomie! #tbt #HappBday2Me lolol"

Talk about a guido in training!

And speaking of diapers, could Ronnie and Sammi be thinking about following in Snooki's footsteps and popping out a mini-guido or guidette? See what they have to say about it and let us know your thoughts on the topic in the comments below!

Catch the next episode of Snooki & JWOWW on Tuesday, March 26 at 10 p.m. ET/PT on MTV.
