Britney Spears fans have demanded veteran journalist Diane Sawyer apologize to her. It came after the airing of Framing Britney Spears, which aired in the US on Friday night.

The exposé explores the dark side of the 39-year-old singer's fame. From her rise as a small town Southern girl, to her pop princess world domination.

Viewers then see the Grammy winner's downfall. We follow the singer's heartbreaking 2007 breakdown and her father Jamie's controversial 13-year conservatorship.

The documentary also shone a light on the #FreeBritney movement.

Sawyer, 75, interviewed Britney in 2003, after her very public break-up with fellow teen star Justin Timberlake.

Sawyer played a clip of Maryland's First Lady Kendall Erlich saying that "if she had an opportunity to shoot Britney Spears she would."

Elrich later apologized for the outrageous statement.

However veteran journalist Diane appeared to gently justify the harsh and shocking statement. Almost implying the hitmaker's "revealing" clothes were a "bad influence" on children.

Britney seemed visibly shocked at the remark, but managed to rebuff the argument by saying: "I’m not here to, you know, babysit her kids."

The interview also focussed on Britney and Justin's high profile breakup.

He all but accused his ex of cheating on him when he released his hit track "Cry Me A River."

The video to the track had a Britney lookalike reaping the consequences of her infidelity.

At the time Britney continued to publicly maintained that she was still a virgin. But Justin suggested otherwise in many post breakup interviews.

In the Sawyer interview Britney was widely seen as the one responsible for the split.

Sawyer even took an accusatory tone, asking her: "What did you do?"

After the airing of Framing Britney Spears, which aired in the US on Friday night, viewers took to Twitter in droves to strike out at Diane. Many branded her a "sl**-shamer."

One fan wrote: "Justin Timberlake laughed and got 'revenge' in cry me a river ...Britney had to go on TV with Diane Sawyer and break down crying in an interview after they broke up...That s**t would NOT fly in today's culture. #FreeBritney."

"I think it’s time for @DianeSawyer to issue a public apology to Britney Spears," said a second added.

"She treated Britney disgustingly and never once said sorry. Speak up sis. You were VERY wrong for the way you interviewed her," a third chimed in.

"Diane Sawyer literally tried to defend a woman who said 'If it wasn’t illegal to shoot Britney I would' to Britney because Britney was wearing 'revealing' clothes and mothers are worried about their children because of it? LIKE WTF???" a comment read.

At the time of Britney and Justin's split, it was rumored she had cheated on Timberlake with dancer/choreographer Wade Robson, now 38.

However, it has also been claimed that Justin cheated on Britney multiple times in the year leading up to their breakup.
