Prince William, Kate Middleton Party Hard In Viral TikTok Clip Of Life Before Marriage [Watch]

A clip of Kate Middleton and Prince William partying hard throughout the U.K. in their 20s, years before they tied the knot, went viral on social media this week.

The viral TikTok clip has been viewed over 4 million times as of this writing and features throwback photos of both Prince William and Duchess Kate looking inebriated after several nights out on the town.

Some of snaps showed the Duke and Duchess of Cambridge leaving London’s exclusive Mahiki nightclub and Boujis nightclub in South Kensington in their younger days, according to Page Six.

"Party hard like normal young people," the caption of the clip read.

Royal fans and TikTok users praised Middleton in the comments section for her stunning looks, both then and now.

"How is she so photogenic! These are the roughest pictures of her in existence and she still looks like a flipping goddess!" one commented. Another added, "Kate didn't age at all."

"She's effortlessly beautiful," a third person wrote. A fourth opined, "She is really the best thing for the royal family. She is a real girl."

A number of users also said they were happy to see photos of the Duke and Duchess of Cambridge just living their best lives with friends and having fun together.

"It's nice to see them happy and relaxed," one user wrote. Another added, "I really love how we have such carefree photos!"

"I can't express how much I love this," a royal fan commented. "I'm glad they got to experience a good time," wrote another TikTok user.

One user cheekily commented that he and his wife were just like Prince William and Middleton in the photos "before mortgage, marriage and kids."

Another joked, "Couples that party together, stay together."

Prince William and Middleton met and dated in 2002 while students at St. Andrews University in Scotland. They briefly split in 2007, but they soon reunited, with the prince popping the big question in 2010 and the couple marrying the following year.

During their engagement interview, the future king revealed how he discovered that he and Middleton were compatible.

"She's got a really naughty sense of humor, which really helps me because I've got a really dirty sense of humor so it was good fun, we had a really good laugh, and then things happened," Prince William told Tom Bradby.

Prince William and Middleton celebrated their 11th wedding anniversary in April. They share three children Prince George, 9, Princess Charlotte, 7, and Prince Louis, 4.
