The adorable Prince George of Cambridge arrived at the private Lindo Wing of St. Mary's Hospital in Paddignton, to meet his new born baby sister.
The 21 months old, first born of the Duke and Duchess of Cambridge, arrived with his father, 34 year old Prince William.
Prince George looked irresistibly cute in his blue attire that coordinated with his father's look.
Prince William himself drove off to pick his first born from Kensignton Palace, where he was being looked after his nanny as his mother Kate Middleton gave birth in the early hours of the morning.
Prince William himself carried the toddler in his arms up the steps of the private wing of the hospital, and Prince George raised his chubby arm in a shy wave to photographers.
The third in line to the British throne was dressed in a pair of blue shorts styled with a navy cardigan, blue socks and black shoes.
33 year old Kate is expected to stay overnight at the hospital before retreating to her Norfolk residence with Prince William and her parents.
