how old is betty

Betty is 24 years old I believe (last 年 her birthday episode was named 24 candles), her birthday is around this time though so she could be 25 now.

I think that Betty is 32 years old because I listen this in an interview.

according to wiki her birthday is april 1984 and she is 25 (i do mean betty not the actress lol)

25 years old
