Nick Carter accused of raping underage autistic fan in 2001

In the lawsuit filed Thursday and obtained by Page Six, the alleged victim detailed that she was invited to the “I Want It That Way” singer’s tour bus following a concert she attended in Tacoma, Wash., after standing in an autograph line.

Ruth then alleged Carter offered her a “red-colored drink” he dubbed a “VIP juice” — even though she was underage — and claimed she now thinks it was a mix of alcohol and cranberry juice.

The “Quit Playing Games” singer, 42, allegedly ordered the then-teen to perform oral sex on him as she burst into tears, per the lawsuit.

Ruth also claimed that Carter took her to a bed on the tour bus, where he allegedly continued to sexually assault her — even though she was a virgin at the time.

The alleged victim said per the lawsuit that she got HPV, a sexually transmitted infection, after the incident. She is seeking monetary damages for the alleged crime.

Following Ruth’s claims, Carter’s lawyer told Page Six in a statement that her allegations are “entirely untrue.”

He added, “Unfortunately, for several years now, Ms. Ruth has been manipulated into making false allegations about Nick – and those allegations have changed repeatedly and materially over time. No one should be fooled by a press stunt orchestrated by an opportunistic lawyer – there is nothing to this claim whatsoever, which we have no doubt the courts will quickly realize.”

This is not the first time the boy band member has been accused of sexual misconduct.
