Britney Spears is back on the top of the charts.

The Princess of Pop’s forthcoming memoir, “The Woman in Me,” shot to No. 1 on Amazon’s bestsellers list Tuesday after she revealed she had an abortion while dating Justin Timberlake.

Spears, 41, took to social media to celebrate the accomplishment and thank her fan base for pre-ordering the book ahead of its Oct. 24 release.

“1 week until my book #TheWomanInMe hits shelves  !!!” she wrote. “Thank you all for making it #1 on Amazon already !!!”

Alongside the message, the Grammy winner shared a promotional video featuring various footage of herself through the years, dubbed with audio from her 2008 MTV documentary, “Britney: For the Record.”

“I’ll have a good book one day — a good, mysterious book,” she said in the decade-old voice-over.

The news comes hours after Spears dropped a bombshell excerpt from her highly anticipated tell-all, in which she wrote about terminating her and Timberlake’s pregnancy in late 2000 when she was about 19 years old.

“I loved Justin so much. I always expected us to have a family together one day. This would just be much earlier than I’d anticipated,” she shared.

“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. I’m sure people will hate me for this, but I agreed not to have the baby. I don’t know if that was the right decision. If it had been left up to me alone, I never would have done it. And yet Justin was so sure that he didn’t want to be a father.”

The “Stronger” singer described the procedure as “one of the most agonizing things” she has ever experienced.

While Timberlake’s rep did not respond to Page Six’s request for comment, sources previously told us that the *NSYNC member, 42, was “concerned” about what his ex was going to disclose from their three-year relationship in her memoir.

“He’s very curious,” one insider told us exclusively Monday. “It’s eating at him.”

A publishing insider, however, shot down reports that Spears attacks Timberlake in her book, telling Page Six that it is “not a takedown” but rather the “Crossroads” star “finally getting a chance to tell her empowering story” after being silenced during her 13-year conservatorship.
