Ronnie may not be on daddy duty just yet (we're looking at you, Sammi), but he still gets to spend quality time with his favorite kid. 

The Jersey Shore star took to Twitter yesterday (January 13), posting a photo of him and his younger sister and writing, "Just laying around with my #PeanutHead #LoveHer #BotherlyLove." What an adorable doppelganger duo!

Do you think Ron and his sis look alike? Let us know your thoughts in the reaction buttons below.
