Inside Prince Harry and Meghan Markle's Secret Wedding Registry (Exclusive)

ET got the inside scoop of what type of items the couple may receive from their closest friends and family.

Martini shakers and energy-efficient light bulbs could be among the fun items on Prince Harry and Meghan Markle’s secret wedding registry!

While the couple has publicly requested charity donations in lieu of gifts ahead of their Saturday nuptials, royal reporter Roya Nikkhah, broke the news in The Sunday Times that the pair also has a gift registry at private members club Soho House.

ET caught up with Nikkhah in the U.K., where she dished on some of the gifts that usually appear on a Soho House wedding registry.

“Beds, bathrobes, but also quirky things like energy-efficient light bulbs and martini shakers and champagne glasses,” Nikkhah says. “There's a real range. We don't know exactly what's on the list -- we can just look at the Soho House to get ideas of what might be on there.”

Soho House is a chain of private clubs, bars and spas in cities including Los Angeles, Barcelona and London. Nikkhah describes the company as a “lifestyle brand of contemporary, cool, chic clubs for the creative industries,” and says it’s a fitting choice for Meghan and Harry.

“I think the fact that they met at Soho House, they obviously love and buy into the lifestyle and the brand,” Nikkhah adds. “We know Meghan was a brand ambassador for Soho House group before she started dating Harry. Her best friend, Marcus Anderson, works with the group, so I think that's the ethos [and] style we're going to see from them going forward.”

Nikkhah notes that it’s perfectly normal that the two have chosen to keep the registry on the down low. In fact, she says that Harry’s brother, Prince William, did the same when he married Kate Middleton in 2011.

“William and Kate, when they got married, asked [people] to make charity donations, but they also had a little list for friends to give them presents that no one really knew about. Very close friends and family.”

Kensington Palace announced in April that the couple wanted well-wishers to make a donation to one of their seven chosen charities instead of sending gifts.

“Prince Harry & Ms. Meghan Markle are incredibly grateful for the goodwill they have received since their engagement, & have asked that anyone who might wish to mark the occasion of their wedding considers giving to charity, instead of sending a gift,” the palace wrote in an official tweet.

The charities include Surfers Against Sewage and The Wilderness Foundation U.K.

With just five days until the two tie the knot in Windsor, England, Nikkhah adds that the British public are embracing California native Meghan with open arms.

“People are really excited about Meghan here,” she says. “She's seen as a real breath of fresh air coming into the royal family. She's going to shake things up a bit; she's going to do things her own way. They are going to be a young, glamorous power couple on the global stage.”
