Gabe Ginsberg/Getty Nick Carter Sued for Sexual Battery in 2001 Fan Incident as Source Denies Allegations Earlier this week, Carter was sued by a woman named Shannon Ruth, who alleged that she was 17 years old when Carter sexually assaulted her on his tour bus after a concert in 2001, when he was 21, according to documents obtained by PEOPLE. The accusation had prompted ABC to cancel the Backstreet Boys' Christmas special, titled A Very Backstreet Holiday, which was scheduled to air on Dec. 14, Variety reported. The special was set to feature Carter and his bandmates, as well as Seth Rogen, Meghan Trainor, Rob Riggle and Nikki Glaser, among others. The band was slated to perform songs from its recently released 10th album, A Very Backstreet Christmas. Want to get the biggest stories from PEOPLE every weekday?

A source close to Carter has since denied the allegations, and Michael Holtz, an attorney for the singer, added in a statement sent to PEOPLE, "This claim about an incident that supposedly took place more than 20 years ago is not only legally meritless but also entirely untrue." Holtz continued, "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." Ruth, who is autistic and has cerebral palsy, claims in her lawsuit that she was waiting in an autograph line after a Backstreet Boys show in Tacoma, Washington, when Carter invited her to his bus. The singer asked Ruth if she wanted a drink, and when she requested apple juice, he gave her a red-colored drink he called "VIP juice," the complaint claims. Though Carter allegedly said the beverage was cranberry juice, Ruth believes it also contained alcohol.

Afterward, the singer allegedly continued to sexually assault her on a bed. Ruth claimed that she was a virgin before the encounter, and that she contracted HPV afterward. In 2017, Carter was accused of rape by former teen pop singer Melissa Schuman, who was 18 at the time. Carter denied Schuman's claims, saying that anything that happened between them was "consensual." He was never charged with a crime, and the Los Angeles District Attorney's office declined the case in 2018, citing an expired statute of limitations.
