The first photos of Britain's Princess Charlotte together with Prince George, who is pictured giving his baby sister a kiss, were released by Kensington Palace on Saturday, June 6.The four photographs, taken by their mother Kate, the Duchess of Cambridge, show 21-month-old Prince George sitting on a sofa holding Princess Charlotte.The portraits were taken when Princess Charlotte, born on May 2, was around two-weeks-old.Propped up by two white cushions, Charlotte appears to be wearing a white romper suit with a matching jumper.Her brother is dressed in a white shirt with blue piping detail around the collar, cuffs and front, and matching blue socks and shorts.

One picture shows George planting a kiss on his sister's forehead, another shows him tenderly looking down at her, a third shows him looking up and a fourth shows him smiling.

The photos were taken at Anmer Hall, Prince William and his wife Kate's country mansion on his grandmother Queen Elizabeth II's private Sandringham estate in Norfolk, eastern England.
