Prince Harry and Meghan Markle are reportedly receiving security protection from the Secret Service on their £1,000-a-night New York trip.
The couple arrived to the city appear at the 24-hour star-studded global TV event Global Citizen Live in Central Park on Saturday.
Making the most out of their journey, they visited the city's highest building - the One World Trade Center, built on the site of the former World Trade Center, and its One World Observatory.
One of the bodyguards escorting Harry and Meghan claimed to be from the Department of Homeland Security.
He was spotted outside the $1,300-a-night Carlyle Hotel in Manhattan on Thursday between jaunts escorting the couple.

The man told a DailyMail.com reporter he was part of a DH security detail, but didn't specify which agency.
Yesterday, Meghan and harry were pictured hand-in-hand as they stepped out in public for their One World trade visit.
Meghan was dressed in an all black outfit including what is thought to be an Emporio Armani coat, with matching black Aquazzura heels and her hair tied back off her face in a bun. Harry also wore a black suit
They met with New York City mayor Bill de Blasio, his wife Chirlane McCray and their son, Dante. They also met with New York governor Kathy Hochul.


It's not yet known what they discussed during their morning meeting. It's thought their sombre-looking outfits were chosen as they visited the 9/11 memorial afterwards.
As they posed for pictures on the observation deck, Meghan was asked if she was enjoying her visit to New York and she replied: "It's wonderful to be back, thank you."
The engagement is the first time Meghan has been seen in public since giving birth to daughter Lilibet in June while the trip also marks the couple's first-ever joint visit to New York City.

Page Six reports Meghan and Harry are believed to have travelled to New York alone and their children two-year-old Archie and three-month-old Lilibet are staying at home in California.
The couple will stay on in NYC until at least Saturday when they will appear at the Global Citizen Live event in Central Park.
At the event, they will "continue their urgent work with world leaders in the pursuit of global vaccine equity to end the COVID-19 pandemic for everyone, everywhere".
