Britney Spears’ affair with Wade Robson was reportedly ‘more serious’ than just a kiss … after pop star admits she cheated on Justin Timberlake in her memoir

Britney Spears’ affair with Wade Robson was reportedly more serious than she claimed in her memoir.

The 41-year-old singer reportedly had a more scandalous affair with a dancer in the early 2000s than the one-time kiss that she finally admitted and detailed in the film Woman in Me.

Her former songwriting partner, Annette Artani, revealed TMZ on Friday that the Tokic hitmaker “wrote and hid a 14-page breakup letter to the dancer.”

Artani — who helped the singer write Evertime in 2003 — recalled that Justin Timberlake, Spears’ then-boyfriend, “discovered it hidden in her makeup bag before she had a chance to give it” to the dancer.

Soon after, the NSINC member broke up with the pop star via text message, leaving her devastated and ‘comatose’ as she revealed in her memoir.

Artani told the agency that the affair lasted longer than a one-night session in a bar because “you don’t write a long letter to someone you just kissed.”

In 2002, Spears and Timberlake were rumored to have called it quits because she was having an affair with an Australian choreographer.

According to The US SunSpears admitted in her memoir that she shared a kiss with Robson during a night out.

“One night we were out and we went to a Spanish bar. We danced and danced,” she recalls in her forthcoming book. ‘I hung out with him that night.’

She pointed out that for years she was completely loyal to Timberlake “with that one exception”.

Spears also wrote in her book that she told Timberlake about the kiss and that they were able to get over it.

In 2001, Robson choreographed her iconic videos Oops… I Did It Again and I’m A Slave 4 U, as well as her live special from Las Vegas.

In 2002, Timberlake ended his three-year relationship with Spears and soon after released the song Cry Me a River.

Spears then released her ballad Evertime – which many believed was her response and her apology.

After excerpts from her upcoming memoir revealed that she had an abortion after becoming pregnant with Timberlake’s child, fans began to speculate that the Evertime song was about Spears losing her baby.

In her bombshell show, which is set to air on October 24, Spears claimed she had the abortion because he “didn’t want to be a father.”

She said she “dreamed of having a family” with the actor and wanted to keep the baby, but he “wasn’t ready” to be a parent and thought they were too young.
