In a follow-up post, the personal trainer revealed some of her fans' answers.
Fan response: Amanda said she had dermal filler injected into her forehead and lips, then asked her followers to guess her real age
Her followers guessed she was 27, 22 and even 14 - the latter obviously being a joke, with Amanda replying: 'If a 14-year-old looked like me, I'd be worried.'
The serious responses varied from mid-thirties to mid-fifties.
After reading several of the guesses, a visibly annoyed Amanda snapped: 'For all of you who said that I was like 40 plus, get f**ked, okay?'
Numbers game: Her followers guessed she was 27, 22 and even 14 - the latter obviously being a joke, with Amanda replying: 'If a 14-year-old looked like me, I'd be worried'
