Prince William brought his two children, Prince George and Princess Charlotte, to visit their new baby brother at St. Mary's Hospital in London on Monday, and Princess Charlotte completely stole the show. 

Walking hand-in-hand with their father, Prince George and Princess Charlotte looked absolutely thrilled to finally being able to meet their baby brother — and Princess Charlotte may have been a little too excited.

The trip was met at the hospital with loads of photographers and members of the media, and Princess Charlotte took the opportunity to show the paparazzi that even though she may be fourth in line to the throne, she is ready to become queen at a moment's notice. 

Princess Charlotte adorably waved for the cameras as she entered the hospital with her father and brother, and even threw in an over-the-shoulder wave just for good measure. This princess is not even 3 years old, and she's already giving the paparazzi what they want.
