Britney Spears has finally opened up about shaving her head

Can you believe it's been 10 years since Britney Spears shaved her head??? What the actual heck.

Britney Spears has finally opened up about her famous head-shaving incident in 2007.

The popstar commemorated the 10 year milestone since she shaved her head by posted a Bible verse on Instagram.

"Love this verse. Something everyone should live by," Spears wrote in the caption of an Instagram photo showing Psalm 126:5, which reads, "Those who plant in tears will harvest with shouts of joy."

Spears, 35, also posted a Throwback Thursday shot of herself holding one of her sons.

"Found this today and realized I'm a very blessed and lucky mommy," she wrote.

Back in 2007 she was in the midst of a bitter custody battle with her ex, Kevin Federline which is when she walked into a haircutting studio and shaved her own hair off (after the hairdresser refused to do it for her).
