He can’t stop the feeling.

Justin Timberlake is “seething” over renewed drama with his ex-girlfriend Britney Spears “overshadowing his new music,” a source tells Page Six exclusively.

“Justin had hoped the backlash [from Spears’ memoir] would’ve blown over by now so that he could focus on his new album, which he’s very excited about, but every day is something new,” the insider says.

Timberlake’s rep did not respond to Page Six’s request for comment.

The former *NSYNC member, 43, came under fire in October 2023 after Spears, 42, revealed in her book, “The Woman in Me,” that she had an abortion during their relationship because he “definitely wasn’t happy about the pregnancy” and “didn’t want to be a father.”

Timberlake has yet to publicly respond to the bombshell, though a source told Page Six exclusively ahead of the tell-all’s release that the “Mirrors” crooner had been “concerned” about what the Princess of Pop would reveal.

The dust seemed to settle after a few weeks of Spears’ fans trolling Timberlake on Instagram, which forced him to disable comments on his account, but the Britney Army was back to their old tricks once the “SexyBack” singer announced his musical comeback in January.

After Timberlake released “Selfish,” the first single from his forthcoming album, “Everything I Thought It Was,” Spears’ supporters successfully campaigned to get the “Toxic” singer’s 2011 song of the same name to No. 1 on iTunes.

Spears, on the other hand, took the high road by praising her ex’s new track on Instagram Monday and apologizing to anyone she “offended” with her bestselling memoir.

Timberlake evidently did not accept the mea culpa, as he issued a pseudo apology of his own during a performance in New York City just two days later.

“I’d like to take this opportunity to apologize to absolutely f–king nobody,” he told concertgoers.

Spears was quick to fire back, slamming the former boy bander online Thursday for “talking s–t.”
