partying at a German FETISH club.
The 25-year-old Twilight star, nicknamed R-Patz, visited Berlin’s infamous KitKatClub in a bid to escape adoring fans’ attentions as he shot his new flick Bel Ami in the city.
Guests there are banned from wearing “normal” clothes.
Instead they are encouraged to don garb such as nipple clamps, metal cage dresses and leather thongs.
Yet when dad Richard heard he’d been there, he revealed he was gagging to visit the sex club with him.
R-Patz, who shot to worldwide fame in 2008 as telepathic vampire Edward Cullen in the Twilight movies, said: “I was telling my dad about it last night and he sounded really into it.
“He told me, ‘I’m coming over — let’s go to the orgy club’.”
The actor revealed he would have no problem visiting the X-rated spot with his dad as he was so close to his family.
He confessed: “They are the only people I really let rip on.”
Guests at the KitKatClub have been known to openly have sex. A source said: “Rob became a fan of the nightclub because he doesn’t get hassled by admirers there.
“The parties in there are crazy, though. It is dark and private so makes a great getaway for him.”
The insider added: “And it’s perfect because on fetish nights — and especially at Halloween — there’s always some people in there dressed up as vampires. The whole myth of biting and sucking blood is a big thing in the fetish world.”
Robert has found success hard to handle since he was launched into the limelight by the Twilight saga.
The worldwide popularity of the film and its sequels has earned him a fortune of at least £32million.
It made him the ninth wealthiest Brit under 30 in last year’s Sunday Times Rich List — above Keira Knightley and Prince William.
He was also voted one of the “sexiest men alive” by People magazine in 2008 and 2009. And Vanity Fair named him “the most handsome man in the world” alongside Angelina Jolie as the most beautiful woman in 2009.
Speaking of his dislike for fame, Robert, whose waxwork is on show at Madame Tussauds in both London and New York, said: “I do everything to hide because, if someone finds out where I am, there are people outside 24 hours a day.
“And that is what drives you crazy, because you can’t escape. My family think I’m crazy.
“The attention makes you not want to go out and then you don’t meet anyone and just get insanely bored. It’s really the boredom that gets to you.”
Robert, who is dating actress Kristen Stewart, plays a 19th century lothario in Bel Ami, out this month.
His character sleeps his way out of his humble French background by bedding co-stars Uma Thurman, Christina Ricci and Kristin Scott Thomas.
