The Duchess of Cambridge may have hundreds of people at her beck and call, not to mention a plethora of celebrities wanting to be her best friend, but Kate knows who her number one BFF really is!
The Duchess often visits Pippa Middleton at the pair's old flat in Chelsea, proving just how strong their sistery bond is!
A source explained to the Daily Mail that Kate always finds time out of her busy schedule to drop by and catch up with Pippa:
"Kate drives over and parks outside and brings her two security guards with her... Pippa likes to have her sister over. They had lunch last week just after they got back from skiing in France."
Sisters are doing it for themselves!
We bet it's nice for Kate to get away from her hectic life as Prince William's wife and get back to her family roots once in a while.
And the girls probably have had a LOT to natter about; what with Kate rumoured to be trying for a baby, and Pippa's blossoming romance with Earl Percy, there's never a dull moment for the Middleton sisters.
