Pink had to deliver her daughter via Caesarean section because she was the breech position.

The 31-year-old singer gave birth to Willow Sage - her first child with her husband Carey Hart - in June and although she wanted to have a natural birth the baby's position meant that wasn't possible.

She said: "She was in the frank breech position, which is head up with her legs up by her head in a pike position. We tried everything to turn her around. Turns out this little girl had other plans - she is my daughter, after all."

Although there were complications during the birth, Pink insists everything went well and has revealed she intends to have a natural birth when she has another child.

Pink added to People: "It all turned out perfectly in the end, even though it wasn't what we intended, because she is healthy and happy and so am I. We'll go for our natural birth next time, for sure."

The 'So What' hitmaker previously revealed she and Carey named their daughter Willow Sage after an "unbreakable" tree.

She explained: "I grew up near one. It is the most flexible tree and nothing can break it - no wind, no elements. It can bend and withstand anything. I love that sentiment and I want that for her.

"Sage is cleansing and sacred and it sounds great with Willow. It doesn't hurt that her last name is Hart - flexible, cleansed heart."
