Kiss frontman Gene Simmons has been accused of sexual battery in a new lawsuit filed in the U.S.

A female employee at one of his restaurants alleged the musician touched her vagina during a photo session in 2016.

The women, who is suing under the name Jane Doe, was working as a dishwasher at one of Simmons' Rock & Brews restaurants when she claims the alleged incident occured.

TMZ.com claim to have to have seen legal documents which claim the woman was encouraged to pose for a photo with Gene, 69, during his visit to the restaurant.

The lawsuit claims the woman's manager encouraged her to move closer to Gene and when she did, the singer allegedly "reached over and forcefully placed his hand on her vagina completely covering it".

The location of the restaurant hasn't been confirmed, although the singer's chain of eateries covers 22 locations across eight states.

The woman alleged Gene acted in a "sexually charged" manner to other female employees, including touching their hands and encouraging them to unbutton their shirts.

Mirror Online has contacted Simmons' spokesperson and lawyer for comment.

Simmons' legal claim came as it was announced on Friday that his mother Flora 'Florence' Klein had died at the age of 93.

Posting a black and white photo of his mother as young woman on his Instagram page, Simmons wrote: "I lost my mother. My mentor. My moral compass. And I am heartbroken. My mother, Flora Klein passed away at 93 years of age.

"No illness,. No pain. She simply quietly went to sleep. My mother will always be in my thoughts and in my heart. Today and forever. And I would urge all of you, to run over, put your arms around your mother, kiss her and tell her how much you love her. Do this every day."

This latest lawsuit comes after Simmons settled another case by a female radio personality, who interviewed the rocker at the opening of his restaurant in San Bernadino, California in November 2017.

In July this year, Gene reached a settlement with another Jane Doe over her allegations that he groped her at the launch.

Prior to the settlement, Gene denied all the claims, saying: "For the record, I did not assault the person making these accusations in the manner alleged in the complaint or harm her in any way."

Last year, Gene hit the headlines for his opinions on women, claiming they needed to use their sexuality to get ahead.

He told the New York Post: "Women have a choice. They can dress in potato sacks, (but) as soon as they pretty themselves up with lipstick, lift and separate them (breasts) and point them in our general direction, they're gonna get a response. Guys are jacka**es - we will buy them mansions and houses... all because of sex."

He also said women needed to "get over your biological urges", adding: "It's natural to want to have kids, but, sorry, you can't have it both ways. You have to commit to either career or family. It's very difficult to have both."

Earlier this year, he apologised for past "arrogant and sexist" behaviour after an Australian journalist accused him of offensive behaviour when she interviewed him in the 1990s.

He said: "You also have to recognise - and this is not a defence, just an observation - it was a different time. So there's no excuse for that kind of language, but it was also a different time' the more arrogant and sexist you were the cooler you were to your fans.

"I've made lots of mistakes you've got to move on and be better. It's time all of us woke up - and I'll be the first to one to admit I've been an arrogant sexist pig."
