She is officially 18. Probably because she can reverse her age by disposing of candy biomass. As seen in Simon and Marcy, their was a pink blob of what looked like bubble gum. She could very well be almost as old as marceline. That would explain how they know each other so well. Plus when the show first started Finn was 12. Now he is 14. And bubblegum doesn't seem to have aged at all.
