Pop sensation Justin Timberlake is gearing up for his highly-anticipated return to the stage with his first U.S. tour in five years, but behind the scenes, he grapples with concerns over potential backlash from loyal fans of his ex-girlfriend, Britney Spears.

The 43-year-old singer, renowned for hits like "Cry Me a River," finds himself in a precarious position following allegations made by Spears in her recent memoir, "The Woman in Me." Spears portrays Timberlake as a callous manipulator and chronic philanderer, alleging that he pressured her into terminating a pregnancy.

"Justin's already faced a big backlash on social media and a blow to the nice guy reputation he's always tried to nurture," a close associate told The National Enquirer. "Now he's going to put himself out there for public scrutiny, and he's really worried this tour could turn into a disaster."

In an attempt to preemptively address the looming specter of controversy, Timberlake plans to broach the topic of his relationship with Spears during some of the initial tour dates, slated to commence on April 29. "He's hoping it will all just go away," divulged another confidant.

However, Timberlake has already felt the sting of Spears' fervent fan base, commonly known as the Britney Army. Following the release of his latest single, "Selfish," fans of Spears propelled a 13-year-old track by Spears with the same title up the charts, creating a formidable challenge for Timberlake.

Despite Spears' recent apology for her scathing portrayal of Timberlake and her commendation of his new music, the singer remains apprehensive about the potential repercussions from her dedicated supporters.

"Britney's revelations boxed Justin into a corner," expressed the friend. "He's really afraid he's going to be hounded by her fans on this tour."

As Timberlake braces himself for the whirlwind of emotions and scrutiny that accompanies a return to the spotlight, he faces the delicate task of navigating the intricacies of his past relationship with Spears while striving to maintain his artistic integrity and reputation.

Most, if not all, fans are aware that Spears and Timberlake, once the epitome of young love, find themselves entangled in a fresh wave of public scrutiny following recent remarks exchanged between the two.

A source familiar with the situation told Us Weekly that Spears, 42, was left unsettled by Timberlake's onstage antics, which took place during his performance in New York City. The 43-year-old singer, known for his chart-topping hits, took a jab at Spears by openly mocking her during his concert.

Timberlake's choice of words, particularly his declaration of not owing an apology to anyone, followed by a rendition of his song "Cry Me a River," widely believed to be inspired by their past relationship, struck a chord with Spears. She took to Instagram to address the situation, expressing her disappointment at the apparent dig while extending an olive branch by praising Timberlake's latest single.

According to the insider, Timberlake's actions deeply affected Spears, marking a significant moment in her ongoing struggles with mental health, which trace back to their breakup years ago.

The turbulent history between Spears and Timberlake dates back to their teenage years when they crossed paths on "The All-New Mickey Mouse Club." Their romance blossomed in 1999, capturing the attention of fans worldwide at the pinnacle of their respective careers. However, their relationship hit rocky waters in 2002, amidst rumors of infidelity on Spears' part.

Timberlake's hit song "Cry Me a River" from the same year fueled speculation about the reasons behind their split, with its lyrics alluding to betrayal and heartache. Despite Timberlake's denial of directly targeting Spears with derogatory remarks, tensions simmered beneath the surface.

In a surprising turn of events in 2021, Timberlake publicly apologized to Spears for his past actions that may have perpetuated sexism or misogyny, signaling a potential thaw in their frosty relationship.

However, the truce was short-lived as Spears reignited the feud with revelations in her memoir, "The Woman in Me," where she disclosed intimate details about their past, including allegations of an abortion and infidelities on both sides.

Timberlake's actions during his Las Vegas concert in late 2023, where he preemptively addressed the song "Cry Me a River" before performing it, further stoked the flames of controversy. Spears responded with a subtle yet pointed jab on social media, hinting at Timberlake's emotional reaction to their past encounters.
