Foul-mouthed Prince Harry screams through haunted house with Jimmy Fallon — as one actor didn’t recognize him

A fright fit for a prince!

Prince Harry cursed up a storm and screamed in sheer fear as he ventured into Jimmy Fallon’s haunted maze in the Big Apple.

The foul-mouth Duke of Sussex joined the talk show host on Thursday’s episode of NBC’s “The Tonight Show,” where the two explored the new haunted attraction, “Jimmy Fallon’s Tonightmares,” at Rockefeller Center.

“Are you easily scared?” Fallon, 50, asked the British Royal at the beginning of the segment.

“Not normally, but today might be different,” Harry, 40, replied before they both walked through the maze with cameras strapped to their chest.

The door leading the duo into the maze quickly opened, and a sinister zombie-like character actor greeted them, prompting the startled Harry to curse just seconds into the spooky adventure.

As they began to walk through the halls of Fallon’s haunted attraction, words appeared on the screen declaring, “There’s a serial killer on the loose.”

Harry then spots a figure in white makeup and black rings around her eyes.

“Is that a panda?” the Duke of Sussex asked, as the knife-wielding figure suddenly jumped from out behind a corner and lunged toward them.

Harry then screams in fear before cursing again as they run off.

“You’re afraid of pandas?” Fallon quipped.

“No! I’m not, I’m not,” Harry replied.

Fallon and Harry were surprised when a werewolf-like creature popped out from a translucent screen as Fallon clutched his chest from the scare.

“That actually got me,” the talk show host said as another werewolf-like creature popped out from a different angle, again causing them both to jump out of fear.

Harry is then seen walking through a fake cornfield, clutching Fallon’s hand out of fear, before they arrive at a zombie drummer growling out at them.

The run-off, but the zombie rocker then appears to break from character slightly and asks one of the following actors at the attraction, “Who was that?”

“Prince Harry,” the actor replied, causing the zombie drummer’s jaw to drop as she fanned herself with her hand out of excitement.

As the two near the end of Fallon’s house of horrors, zombie-like figures begin popping out from all directions.

“Jesus f–k,” Harry shouted as he finally exited.

The talk show host then pointed at a camera and asked the prince to take a picture.

As Harry and Fallon posed for a photo to celebrate surviving the haunted house, a sinister-looking creature burst out of a frame on the wall behind them.

Harry screamed and balled up his fist as if he was going to strike the actor out of pure fear before the segment ended.

Harry’s appearance on the late-night show comes after he celebrated his 40th birthday on Sept. 15.

The milestone celebration was extra special for the estranged royal, who received a massive $8.5 million cash bonus , thanks to arrangements made by his late great-grandmother, Queen Elizabeth the Queen Mother.

Harry’s family sent him birthday wishes on social media, the first time they had sent such a message to King Charles’ youngest son in three years.

The Duke of Sussex was in New York this weekend, where he is scheduled for several events, including The Diana Award.

He set to jet back to the UK, where he will be the guest of honor for the WellChild Awards in London on Sept. 30.
