Britney Spears is showing her support for ex-boyfriend Justin Timberlake.

Timberlake, who dated Spears from 1999 to 2002, has been vilified by some Spears fans after she made some serious claims about him in her memoir, but now, the “… Baby One More Time” singer is coming to his defense.

“I wanna apologize for some of the things I wrote about in my book,” Spears wrote on Instagram last night. “If I offended any of the people I genuinely care about I am deeply sorry…”

She continued in part, “This is actually a book I didn’t know needed to be written … although some might be offended, it has given me closure on all things for a better future !!! Hopefully I can enlighten people who feel particularly alone in most cases or hurt or misunderstood !!! Again, my motive for this book was not to harp on my past experiences which is what the press is doing and it’s dumb and silly !!! I have moved on since then !!!”
