The royal family are known for leading very private lives behind closed doors, so it's rare for us to discover a little insight into their family affairs.
We all know and love the royal's gorgeous Spaniel Lupo, but we certainly weren't aware that one-year-old Princess Charlotte has her own pet.
The toddler apparently has a tiny hamster called Marvin.
The Duchess of Cambridge revealed the family secret during a visit to the Magic Garden playground at Hampton Court Palace in London.
Whilst officially opening the gardens, the Duchess reportedly told a pupil from Hampton Wick school that "Charlotte really likes it because the whiskers always tickle her face."
Whether you like the name or not, the news is seriously cute!
