One day after the "Cry Me a River" singer appeared to take aim at his ex at his Jan. 31 concert, telling the crowd, "I'd like to take this opportunity to apologize to absolutely f--king nobody" before reportedly launching into his 2002 hit, Britney fired back with some stronger thoughts of her own.
"Someone told me someone was talking shit about me on the streets!!!," she wrote on Instagram Feb. 1 alongside a photo of the moon framed inside a basketball net. "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!!!"
Amid the drama, the "Toxic" singer made her Instagram account private.
Justin has been under renewed scrutiny following the release of Britney's memoir The Woman in Me in October. In the book, she gave insight into their three-year relationship, sharing she was pregnant with the *NYSNC alum's baby and got an abortion, as well as revealing Justin broke up with her via text in 2002.
However, recently Britney seemed to be trying to clear the air, praising Justin's new music and reflecting on the how her book may have been perceived.
"I wanna apologize for some of the things I wrote about in my book," the 42-year-old wrote on Jan. 29 in a since-deleted post. "If I offended any of the people I genuinely care about I am deeply sorry."
"I also wanted to say I am in love with Justin Timberlake's new song 'Selfish,'" she continued. "It is soo good."
For his part, Justin has kept mostly quiet following Britney's book, but previously offered an apology to Britney after the release of the documentary Framing Britney Spears.
"I am deeply sorry for the time in my life where my actions contributed to the problem, where I spoke out of turn, or did not speak up for what was right," the 43-year-old wrote on Instagram in 2021. "I understand that I fell short in these moments and in many others and benefited from a system that condones misogyny and racism."
