I've never booked her, but saw & spoke to her very briefly when visiting Gabriela at Milton Keynes.
She's obviously very intelligent & you could have a good conversation with her, comes across as a very nice woman. From my limited experience, I'd not say they generally use heavy airbrush at HoD / MKE, several of the girls look just as good when you see them for real. (Others disagree with this though, I may not have an accurate impression.) With Olivia, even I'll say that all the pics of her I've seen are heavily airbrushed. Looks mid or possibly even late 40s when you see her in the flesh. That said, still a good looking woman in a Milf sort of way. Not seen her topless, but was in revealing underwear, I'd be 70% confident her tits are real. Good large tits, I'm sure they look great when gravity is on their side, e.g. if you have her in doggie.
