Earlier this month, we marvelled at Beyonce's post-baby figure just one month after giving birth to Blue Ivy, and for the past few days we've been shocked at Amanda's thin figure.
Amanda was rushed to hospital whilst working on BGT, and gave birth to Hollie on 23 January.
She was in a critical condition for three days, but returned to work amazingly quickly.
On 11 February, just three weeks after Hollie's traumatic birth, Amanda was back with her BGT co-judges in Edinburgh.
She kept covered up when not at the auditions, but dared to bare in a sleeveless peach top when she was in front of cameras.

Amanda then went for broke and bared her legs this weekend in Birmingham. She wore a lacy blue dress on Friday, and a hot red tight number on Sunday. Wowzers.
Amanda has been tweeting pictures of her newborn too, first introducing Hollie to the world on Twitter two weeks ago, on 6 February.
She then tweeted another picture of her cradling Hollie as she took her new daughter to visit her old Shrek castmates at the Theatre Royal Drury Lane on her birthday last Thursday.
We don't know how she's done it, but Amanda is looking uh-may-zing.
