Prince Louis and Prince George are the image of each other in this adorable side by side snap.

Prince Louis turned one in April of this year and apart from his debut on the steps of the Lindo Wing, his christening and his official birthday snaps, the little tot has been kept out of the public eye for the most part What we didn't notice at the time is how similar he and his older brother Prince George are and when you see them up close, it's almost uncanny. This latest side-by-side snap features on Instagram fan account loveprincessdiana and it's just adorable altogether. I mean, the facial expression is the exact same. There's a second snap featuring the two brothers together with their sister, Princess Charlotte, the middle child in the Cambridge family. Again, there are noticeable similarities between the three siblings and we can't say we ever really noticed them before. A royal source said previously that Charlotte loves being a big sister to Prince Louis and they have a "great bond" According to Us! Weekly, the little girl is mad about her younger brother and won't leave his side. The insider said that Princess Charlotte is just like her older brother, Prince George, and now Charlotte is getting on great with her younger brother, just like George did with her.

"Charlotte is just like him. They have a great bond, and a similar connection is growing between Charlotte and Louis."
