The clip is of special significance though, as it was taken on Tuesday, October 23 - Prince Louis' six month birthday.
The couple were travelling from their country residence, Anmer Hall in Norfolk, back to London to attend the Queen's State Banquet being held for the Dutch Royals.
All eyes were on the Duchess of Cambridge, who wore the Cambridge Lover's Knot tiara - a favourite of late mother-in-law Princess Diana.
So far, we have not given many glimpse's of the Cambridge's youngest child.
The most recent was pictures released by the Royal Family following the christening.
And who could forget the sweet kiss planted on Louis' forehead by adoring big sister, Princess Charlotte.
