Even though Prince Harry and Meghan Markle's wedding has already come and gone, the media is still keen on discussing this year's biggest event.

From the fashionable outfits to the delectable menu and the speeches at the reception, royal watchers noticed the appearance of Harry's cousins, and no we're not talking about Princess Eugenie or Zara Phillips.

We mean Princess Diana's side of the family, who stole the show with their obvious charm and stunning good looks at the most talked about ceremony.

Let's take a peek at who's who on Diana's side of the family.

Lady Kitty Spencer

The moment Lady Kitty Spencer showed her face at the royal wedding, people around the world couldn't get over her striking beauty - and her uncanny resemblance to the late Diana.

She's the oldest child of Charles, 9th Earl Spencer and Victoria Aitken, and has already made a name for herself in the fashion industry.

She began her modelling career in 2015, when she appeared on the cover of Tatler magazine. Even her father wasn't a fan of her sexy photo shoot, she still decided to pursue her dreams and signed a contract with Storm Model Management.

Since then she's become the muse of the high fashion label, Dolce and Gabbana, and has walked in the brand's runway shows.

But despite being named, it doesn't mean Kitty isn't a smart cookie either.

Not only did Kitty study politics, psychology, and English literature at the University of Cape Town for her undergrad, she then went on to complete her master degree in luxury brand management from the European Business School at Regent's University London.

When Kitty isn't setting her sights on conquering the fashion world, she's a philanthropist who is involved with Centrepoint, a charity for homeless young adults, and is a trustee for Give Us Time, an organization that gives British servicemen the opportunity to enjoy a vacation with their loved ones.

Louis Spencer, Viscount Althorp

Next on the list is Louis Spencer, Viscount Althorp, Kitty's 24-year-old brother.

Like many of his royal relatives, Louis was born at the Lindo wing of St Mary's Hospital in London, on March 14, 1994, and will eventually inherit the title of Earldom of Spencer (which will make his future wife a countess).

Like his sisters, he grew up in the Constantia area of Cape Town, South Africa, but has since moved across the pond to Scotland.

While Louis is a student at the the University of Edinburgh, little else is known about the viscount. He doesn't have any public social media accounts, but has appeared on plenty of others, including Nicki Minaj's Instagram page, where the rapper joked about marrying the handsome man in 2015.

"Check out our wedding photo. 😂😂😂😂 👸👸👸👸👸👸👸❤️ no honestly it was such an honor to have you guys. 🙏," Minaj captioned the photo.

But, when the internet got wind of Louis' good looks, they took to Twitter to let their attraction to him be known - declaring him as the world's most eligible bachelor.

Lady Eliza Spencer and Lady Amelia Spencer

While 25-year-old twins Lady Eliza Spencer and Lady Amelia Spencer haven't gotten as much time in the spotlight as their brother and sister, they have already accumulated plenty of media attention on their own.

Well, when we say both of them, we primarily mean Amelia, and it's definitely not for a positive reason.

Back in 2011, Amelia almost missed her cousin Prince William and Kate Middleton's wedding (she was also a no show at Harry's), after she was accused of attacking a man on crutches.

Amelia had allegedly become infuriated after a taxi cut her off in a McDonald's drive thru lane, and started "swearing, smacking, and kicking" the driver.

Luckily, the charges were eventually dropped and Amelia was able to fly out to London and attend the monumental event.

While Amelia faced the law, her sister Eliza had already dealt with her own upsetting past.

Just before her 16th birthday, Eliza's first serious boyfriend, Christopher Elliot, died in a car accident, leaving her, Elliot's family, and his surfing community in immeasurable grief.

In 2016, Eliza was also rumored to tie the knot with her boyfriend of financial analyst, Matthew Rozowsky. But after five years together, Eliza called off their engagement, and is currently back on the market.  

Charles Spencer, 9th Earl Spencer

Even though he's no longer a looker, it's only right we round off this list with Charles Spencer, 9th Earl Spencer and Diana's younger brother.

Having tied the knot on three separate occasions, Charles was first married to Victoria, a former model, and had the four beautiful children mentioned above.

As their divorce might tell you, the couple didn't have a healthy relationship, and Charles was caught having extramarital affair only six months after Victoria had given birth to Kitty. It was also revealed the mother-of-four was battling an alcohol and heroin addiction, and was suffering from anorexia and bulimia.

After he divorced Victoria in 1997, he married Caroline Freud in 2001, where they welcomed Edmund Charles Spencer and Lady Lara Spencer, into the world. Sadly, they too would part ways only six years later.

However, the Earl seems to have finally found happiness in the likes of Karen Gordon, who he wed in 2007 - only months after he called off his engagement to Bianca, Lady Eliot.

The couple share one daughter, Lady Charlotte Diana Spencer, who is five years old.
