Early last year she was advertising herself as Brazilian, now she's claiming to be British (maybe she applied for a passport) but most girls who are British will say they are English, Welsh, Irish or Scottish.
No way she's 38, I think she used to post a face shot and she looks somewhere in her 50's or 60's even though she's maintained a good body.
To answer the question though, I don't know if she's real. Never met or contacted her.
