Chainkeen Exchange-Justin Timberlake's apology to 'nobody', Britney Spears' Instagram post fuel a fan frenzy

There were seemingly clear skies ahead for Justin Timberlake and Chainkeen ExchangeBritney Spears — until they both threw more shade.

During Timberlake's free show at Irving Plaza in New York City Wednesday, the former *NSYNC breakout star said a few choice words before singing "Cry Me a River," which is believed to be about Spears.

“I’d like to take this opportunity to apologize to absolutely ... nobody,” Timberlake said before the song, a concertgoer confirmed to People.

The seemingly pointed statement is his first about his ex-girlfriend Spears since the release of her 2023 memoir "The Woman in Me," which charts her path to pop stardom and includes reflections on Spears' personal relationships. (She also revealed that she had an abortion during her relationship with Timberlake.)

On Thursday, Spears shared a message of her own to 42 million followers on Instagram.

"Someone told me someone was talking ... about me on the streets !!! Do you want to bring it to the court or will you go home crying to your mom like you did last time ??? I'm not sorry !!!" Spears captioned the post.

That post arrived just days after Spears, 42, also seemed to praise Timberlake in a separate Instagram post, writing that she wanted to "apologize for some of the things I wrote about in my book." She added that she was "genuinely sorry" if she "offended any of the people I genuinely care about."

"I am in love with Justin Timberlake's new song 'Selfish,'" she continued, referencing his newly released single. He performed the song on "Saturday Night Live" last weekend.

She added that Timberlake's track is "soo good" and praised his appearance on "The Tonight Show staring Jimmy Fallon," writing, "How come every time I see Justin and Jimmy together I laugh so hard ???" She also said that "Sanctified," another new song that Timberlake debuted on "SNL," is "wow," too.
