Spears and Timberlake went on to date from 1999 to 2002, but their relationship began to bloom behind the scenes onThe Mickey Mouse Club.

“[Once] at a sleepover, we played Truth or Dare, and someone dared Justin to kiss me,” she writes. “AJanet Jacksonsong was playing in the background as he leaned in and kissed me.”

The “Toxic” singer also reveals inThe Woman in Methat while the show was “unbelievably fun,” it also was “exceptionally hard work,” with the kids expected to practice choreography and routines “thirty times in a day.”

Spears’ new book release follows the 2021 termination of her13-year-long conservatorship, which Timberlake also spoke out about in June of that year. After Spears revealed she wanted “to end the conservatorship,” the *NSYNC alum wrote to his fans on social media that “we should all be supporting Britneyat this time.”

“Regardless of our past, good and bad, and no matter how long ago it was… what’s happening to her is just not right,” he wrote. “No woman should ever be restricted from making decisions about her own body. No one should EVER be held against their will… or ever have to ask permission to access everything they’ve worked so hard for.”

“Jess and I send our love, and our absolute support to Britney during this time,” he shared. “We hope the courts, and her family make this right and let her live however she wants to live.”
