And just to rub it in, the 45-year-old star shared a snap of her in a tiny two-piece enjoying a sunshine break somewhere exotic.
We’re guessing it’s not Blackpool.
But after posting the pic on Instagram, eagle-eyed fans noticed there was something not quite right about the snap.
Take a closer look at that horizon. Yep, definitely dodgy.
One fan wrote: “Since when did the oceans horizon have curves? Photo shop fail (sic).”
“Why is the horizon got a big hump in it? What happened? Did the see rise for her? (sic),” another added.
Mandy has since deleted the snap, but not everyone had a problem with it.
“All the jealous keyboard warriors out in force as usual....fair play Amanda still a total cracker at 45!!!" one fan commented.
We’d have to agree, and Amanda proved she didn’t need any help from Photoshop last week when she posed completely naked - and un-airbrushed - for PETA’s latest campaign.
The actress and presenter stripped to her birthday suit in a bid to encourage more of us to become vegetarians.
Amanda, who has been a veggie since her early teens, also spoke of the benefits of not eating meat, crediting the lifestyle with helping her to keep in shape.
