So much for trying to redeem himself. Justin Bieber may be back to his old dicky ways once more, and here comes an alleged story about him molesting a Playboy Playmate. Sarah Harris was doing an interview with The Edge 96.One's Mike E & Emma when she told the story.

Apparently, she tried to help Bieber out, but only to end up having him cop a feel.

Quickly. she extended her backhand to meet his face. Here's the story:

Justin thanked Sarah for defending him, hugging her and giving her a kiss on the cheek before suddenly making an unwanted advance as he made his way out of the party with reality star Kylie Jenner.

“And then he grabbed my boob! And it was my instant reaction to just backhand him across the face,” Sarah insisted.

The statement was met with a roar of laughter from the breakfast show duo, with Mike E exclaiming, “so he is a cheeky little b*st*rd!” before Emma interjected with, “That’s invasive!”

“He kind of freaked out and didn’t even say anything and then Kylie Jenner pulled the finger at me and then security took them both out,” she insisted smugly.

Three days later, Justin sheepishly returned to the Playboy mansion and apologised to the her, she says.

He apologized because he didn't want this story out there. But now it is. Here's more of Sarah Harris:
