The singer is already mother to an 18-month-old daughter, Willow, with her motocross star husband Carey Hart, and has previously voiced a desire to adopt.
Now she has revealed she wants four more kids, and cites Angelina Jolie and her partner Brad Pitt as an example of her ideal family unit.
Pink tells Britain's Celebs on Sunday magazine, "I'd like five kids. I want to adopt. We have four rescue dogs and we'd like some rescue children as well. How amazing are Brad and Angelina? I don't know how they do it. I have one kid and I'm exhausted. I don't do one-sixteenth of what that woman does... I don't want 18 children, I want five. Carey is super into it. I'm like, 'Carey, can you give me a mixed baby?' He's like, 'I cannot physically give you a mixed baby!'"
Jolie and Pitt are parents to three biological children, as well as three adopted kids.
