Timberlake also apologized for tearing off a part of Janet Jackson's dress at the 2004 Super Bowl and exposing part of her breast.

While this was said to be an accident at the time, the Daily Mail reports, Janet was publically vilified for the now-notorious incident.

Timberlake said wrote in a lengthy Instagram post:

"I've seen the messages, tags, comments, and concerns and I want to respond. I am deeply sorry for the times 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. I understand that I fell short in these moments and in many others and benefited from a system that condones misogyny and racism.

"I specifically want to apologize to Britney Spears and Janet Jackson both individually, because I care for and respect these women and I know I failed."

The 40-year-old's apology comes after he was tagged in a number of social media posts criticizing his treatment of Spears following the release of the new documentary about her conservatorship battle, Framing Britney Spears.

As per the Daily Mail, the documentary, according to Spears' fans, lays bare how she has been repeatedly exploited by the men in her life.

Timberlake is accused in the documentary of being one of the men who let Spears down, having dated the singer from 1999 until 2002 after first meeting at The Mickey Mouse Club when they children.

At the time of the split, it was alleged that Spears had cheated on Timberlake.

His career received an incredible boost as a result as he sang songs about heartbreak, all promoted under the narrative that he had been crushed by Spears' actions.

Timberlake even featured a Spears lookalike in the 2002 video for Cry Me A River.

It is not known if Timberlake has privately apologized to either of the women, but neither of them has publicly responded to his apology.
