Well, we were in the same year at school, so she is 1980 or 1981 ... def not 1986 as that would make her younger than her younger siblings iyswim! All the press says Rebel Wilson is her real name so I guess she just officially changed her original first and last names at some point. It is really neither here nor there - I always really liked her and thought she was/is very clever and funny. I remember when she told me her stage name and I was a bit mmmm, that is a little silly but I didn't realise she was going to focus on comedy so a funny name helps! At some point, her real name/age will come out as there were too many of us at school/uni with her before she fully adopted the persona. But it really doesn't matter - she is awesome and I am a big fan (from afar these days as we didn't keep in touch)! I can't remember her siblings names but pretty sure Ryot and liberty are not what they were born with.
She is so so funny! I love her! In all fairness though, Rebel may be her real name now in the sense that she officially changed it but it is not the name she was born with. She was originally a Melanie, also had a different last name. Funny thing is, her wiki page also says her date of birth is 1986 ... this is also not correct (we were at school together) but I guess that is Hollywood for you. Super happy she is getting a lot of attention now - she really is talented!
