The royal family matched in varying shades of blue for the portrait, which was taken earlier this year at their home in Kensington Palace by royal photographer, Chris Jackson.
The gorgeous family photo quickly caught the attention of royal fans, who compared Charlotte to her great-grandmother Queen Elizabeth II.
The resemblance really is uncanny!
The release of the family's official portrait also came with an update on Charlotte's education, with Prince William and Kate announcing that the Princess will be starting nursery school in January 2018.
The two-year-old will attend Willcocks Nursery School in London which is "delighted" to accept the Princess as a new student.
"We look forward to welcoming Charlotte to our nursery in January," Willcocks Nursery School said in a statement.
We can't wait to see Charlotte kitted out in her pre-school gear, just like her big brother George in 2016.
