Britney Spears apologized on Instagram for some content in her memoir, "The Woman in Me."

The apology was directed at people she genuinely cares about, and she subsequently made her Instagram account private.

The apology caption accompanied a video clip of Justin Timberlake on The Tonight Show with Jimmy Fallon.

Timberlake is on a promotional run for his upcoming album, with the lead single "Selfish" released.

Spears expressed admiration for Timberlake's new song on Instagram.

The memoir revealed that at 19, Spears unexpectedly became pregnant, and Timberlake pushed for her to end the pregnancy.

Spears and Timberlake stayed together for two years after Spears had an abortion.

Timberlake has not officially responded directly to Spears' memoir.

Before the memoir's release, Spears tried to address the anticipation, stating that most of the content is from 20 years ago, and she has moved on.

Justin Timberlake's new single release, "Selfish" is this week's favorite new music choice with 77% of the vote, according to a Billboard poll.
