Britney Spears reveals she had abortion while dating Justin Timberlake

Britney Spears' bombshell claim that she had an abortion is detailed in her upcoming tell-all book, 'The Woman in Me.'

Britney Spears has revealed that she got pregnant while dating Justin Timberlake and had an abortion when he decided that they were “way too young” to have a baby.

The bombshell report, first detailed by People, comes via Spears’ upcoming memoir, The Woman in Me. (The book is out on Oct. 24.)

“But Justin definitely wasn’t happy about the pregnancy. He said we weren’t ready to have a baby in our lives, that we were way too young,” Spears writes of the decision to terminate the pregnancy in the book, according to the outlet.

Spears and Timberlake began dating in 1999, when she was 17 and the *NSYNC alum was 18. They dated until 2002.

After their split, Spears went on to briefly marry her childhood friend Jason Alexander in a surprise ceremony in Las Vegas in 2004, but the marriage was annulled just 55 hours later.

Nine months later, she married backup dancer Kevin Federline, and eventually had two children with him — Sean Preston, now 18, and Jayden James, now 17.

Timberlake has yet to publicly comment on the contents of Spears’ memoirs.

The Woman In Me hits shelves next week, and Spears has promised a no-holds-barred tell-all for her fans.
