Rihanna shares some royal wedding night advice for Meghan Markle & Prince Harry (Exclusive)

Rihanna's got some wedding night advice for Prince Harry and Meghan Markle!

The 30-year-old singer launched her lingerie collection, Savage X Fenty, with a pop-up shop in New York City on Thursday, and already has some pieces in mind for the royal spouses-to-be.

In an interview with ET, Rihanna said her gift for Meghan and Harry -- whom she met with in Barbados during his Caribbean tour in 2016 -- would be pretty "extreme."

"I think you have to go to the extreme when you're gifting both for a man and a woman, because both people benefit from the gift," Rihanna teased, before previewing her collection.

"We have a bridal vibe going on, we definitely do have a little skirt and top situation," she said. "But I mean, really, on your wedding night, you could do whatever you want. It depends on how savage you wanna be."

Rihanna's line doesn't just have sexy gifts for the wedding night. Her collection includes items for "everyday situations."

"[The line has] sexy gifts for your girlfriends, whether you're a man, whether you're a woman, whether you're just a best friend. The best gift is lingerie, we all want that," she said. "There's a lot of stuff that feels really comfortable, comfortable enough to wear under like a T-shirt and jeans. You need those everyday situations, and you need the stuff that takes you out of your box."

The Barbadian beauty definitely knows how to take things to the next level. She absolutely slayed the 2018 Met Gala while co-chairing the event on Monday in a Pope-inspired Margiela Artisanal gown by John Galliano. The look was intricate and impressive, and according to RiRi -- pretty darn heavy.

"It was heavy, every step was a squat," she joked. "I promise you my butt gained from that night."

"I had another option that was a lot more simple, same Margiela, but I felt like it was an insult to the people who sat there and like, hand beaded that entire thing, to just say, 'No, put that in the archives," she explained. "It was so great, I couldn't deny it."
