The TV presenter, 29, has regained her petite figure after giving birth to daughter Ava last August and didn't have to resort to any faddy diets.
'I think breast-feeding helped – and running up and down the stairs all day,' she tells the Daily Mirror.
Sadly for Myleene's partner Graham Quinn, her baby boobs have disappeared, too.
The former Hear'Say singer, who became an over-night pin-up when she appeared on I'm A Celebrity, boosted her amazing cleavage while she was expecting.
Now she's still curvy but back to her slimline self.
