And now another celeb has signed their name on the doll-making dotted line - Mariah Carey.

The singer, who is currently enjoying a massively successful comeback in her career, has revealed a set of dolls will be made in her likeness.

But fans might struggle to get their paws on one - they are strictly limited edition, as an insider told the Daily Mirror:

Quite.
