You're right, no way is she 21. I don't understand why some of the 14 year olds have to be 14 for six years, while some of the 16 year olds are passed off as age 21.
She's 22. She looks younger as she's got a round fresh face. Though if she parties/smokes like this for another 10 years, she'll age fast! When I was her age, I couldn't get into nightclubs cos I looked underage - bah!
