There's a new celebrity cat in town!

Katy Perry took to Twitter to announce that she and fiancé Russell Brand recently purchased a new cat together – an adorably tiny kitten named Krusty.

Perry and Brand each have a cat of their own – she Kitty Purry, he Morrissey – but the couple told PEOPLE in February that their fuzzy felines just don't get along. Perhaps Krusty will be the peacemaker this growing family needs?

Calling Krusty a "third child," cat-crazy Perry told Twitter followers over the weekend she was "proud" of the furry acquisition. Here's wishing the couple at least nine lives of happiness with their new pet!
