Britney Spears is shedding light on her journey as a mother.

The pop star has two children with her ex-husband, Kevin Federline.

Britney first became a mom in 2005 to her first son, Sean Preston Federline, and welcomed a second son, Jayden James Federline, in 2006.

The singer revealed she breast fed both of her children with a risqué-looking post on Instagram.

On Monday, March 14, Britney posted a photo of her chest in a black lacy bra.

She included a message about breast feeding.

“Okay… so I breast fed my 2 boys…like a freaking milk factory,” she wrote.

“I was always spraying out and leaking because I was so full of milk and it kind of hurt my boobs!!! They got so full so I was like, ‘Hey I will make a milk factory in my living room’ and guess what… I did!!!”

Britney went on to say that 13 years later she got through it, and that she and her breasts are wiser now.
