Just call him the Gropinator.

“Terminator” star Arnold Schwarzenegger has been accused in a third groping incident while on a publicity tour in London.

The hubby of TV reporter Maria Shriver allegedly got a bit too frisky with gorgeous Melanie Sykes, the hostess of the British TV show “Celebrity!”

The Sun in England newspaper reports that Sykes was chatting with the famed muscleman when, as cameras rolled, he grabbed her around the waist.

She pushed his hand away, saying: “Get your hands off me – I’m scared.”

But moments later, it was back, inching up toward her breast, the newspaper said.

The star’s spokeswoman, Jill Eisenstadt, denied her client had done anything inappropriate with Sykes, or two other women he allegedly fondled.

“I wasn’t there. I don’t know this woman. But he’s always had a great relationship with journalists, and he’s always acted appropriately . . . I just don’t believe it for a second,” Eisenstadt said.

Still, Sun gossip columnist Dominic Mohan has dubbed Schwarzenegger “The Octopus,” awarding him a “Groper Of The Year” award.

Schwarzenegger – in Britain promoting his sci-fi flick “The 6th Day” – has also been accused of pawing TV hostesses Anna Richardson and Denise Van Outen.

The married father of four conducted the touchy-feely interviews with Sykes, Richardson and Van Outen on the same day in a suite at The Dorchester in London.

He allegedly grabbed Richardson and said: “You don’t get the big money for nothing.”

“The guy’s a groper and is totally unprofessional,” Richardson, 29, told The Sun.

“I wanted to say, ‘You dirty bastard.’ But you can’t tell a powerful man like him to f- – – off . . . He kept saying how fantastic I looked and staring at my [breasts].”

When their interview ended, “He pulled me onto his knee, saying ‘I really want to know if your breasts are real.'”

That’s when Arnold allegedly took matters into his own hands. He then said of her triple-D breasts: “Yeah, they are real,” Richardson recalled.

Eisenstadt said Richardson made her complaint only after movie company Columbia Tri-Star banned her from future interviews because of alleged bad behavior during the interview.

“They requested that she not be invited back, and then it just kind of snowballed. It seems a little fishy to me,” she said.

Schwarzenegger’s lawyer, Marty Singer, called all the complaints an “outrageous fabrication” by “people trying to get their 15 minutes of fame.”

He said Richardson “is the one who basically came on in a very provocative manner to Mr. Schwarzenegger . . . asking him to basically check her out. She left in a very happy mood.

“It’s a case of three people getting their name in the paper . . . Quite frankly, my client didn’t do anything inappropriate.”
