The singer - whose real name is Alecia Moore - and her husband Carey Hart take 13-month-old daughter Willow on tour with them and claim that they still party with her in their company.
However, Pink admitted that their idea of fun is different now that they have a baby.
She told Philadelphia's Q102 radio station: "We wake up and dance. [We] party naked in the hotel room."
Pink confessed that although she misses the alcohol element of her partying, she is glad not to be smoking.
She revealed: "It's a different kind of partying. It used to be whiskey, tears and cigarettes. Now it's [my baby's] kind of tears, no cigarettes and the colour of poop. Pure joy. I miss the whiskey, not the cigarettes."
