Pink gorged on cheesecake and chicken wings during her pregnancy.
The 'True Love' singer loved being pregnant with her daughter Willow, now two, because it meant she could indulge in her favorite fattening snacks without feeling any guilt.
She told Closer magazine: "I put on nearly 50lbs and it was awesome. I knew that as soon as I got pregnant I was going to eat cheesecake and chicken wings - and I did. I gained every one of those pounds. But I thought I'd lose it a bit easier."
Pink hired celebrity trainer Jeanette Jenkins and 'The Biggest Loser' star Jillian Michaels to help her shed her excess pounds. She also signed up to food delivery service Freshology, which limited her to 1,200-1,400 calories per day and quickly regained her toned abs thanks to all her hard work.
The 34-year-old star explained: "I train five days a week for an hour and a half, plus rehearsals if I'm touring - but I eat a lot too. I like food and I like my wine, so I don't let it stop me from enjoying myself."
The feisty singer also said she and her husband Carey Hart can never bring themselves to leave their daughter at home with a babysitter, so end up taking with them everywhere they go.
Pink quipped: "We'll talk about going out but, if we do, were always a threesome with Willow. Carey's like, 'You want to leave her at home?' and I'll say, 'Nope, she's coming.' We're attached at the hip."
