Britney Spears writes of abortion while dating Justin Timberlake in excerpts from upcoming memoir

Britney Spears wrote that she had an abortion while dating Justin Timberlake more than 20 years ago, according to a peek inside her hotly anticipated memoir.

“If it had been left up to me alone, I never would have done it,” she writes of the procedure, according to the excerpt from “The Woman in Me” published Tuesday in People magazine. “And yet Justin was so sure that he didn’t want to be a father.”

The pregnancy “was a surprise, but for me, it wasn’t a tragedy,” she wrote in the excerpt, saying that she had wanted to start a family with Timberlake — it was just earlier than expected.

“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,” she wrote. The couple broke up in 2002. It’s unclear when the pregnancy happened.
