Yesterday, Facebook released their 2013 Year in Review report, featuring the most talked about topics of the year. And while some make perfect sense, we're still in shock over others!

You'd guess Kate Middleton, Prince George, Kim Kardashian, and Miley Cyrus were shoo-ins, right? And come on, Fifty Shades of Grey had to make the list! Well, not so fast. Prepare to be wowed, because here, we're tackling what actually turned out to be the world's most buzz-worthy subjects ...

The same week she was spied wearing a tiara and hitting the red carpet for a movie premiere in full-on, regal mode, Kate Middleton tended to a far less glam but even more heartwarming duty yesterday: Visiting gravely sick children and their parents at the Shooting Star House Children's Hospice. And in her effort to spread early Christmas cheer, the Duchess didn't rely on shaking hands and kissing babies alone ...

Kate also got involved with a music class, art therapy session, and also stole little ones' hearts by entertaining them with a frog puppet! Ha! Who knew the new mom had such awesome puppeteering skills?! 

Not exactly the same pramWell look who was out and about the other day! Kate Middleton took Prince George out for a stroll through Kensington Gardens in their fab pram -- which just happens to be a navy blue $2,350 Silver Cross carriage. There she was, in sneakers, jeans, and a casual jacket, with her dog Lupo, looking just like any other mom we might know. Except, of course, just a wee bit more stylish, and there is that small matter of having the future King of England in that stroller!

Anyway, you can check out the action via PopSugar's photos of Kate Middleton and Prince George. They will make you swoon -- Kate shuffling through the autumn leaves with her little one. So sweet! And that really is a carriage fit for a prince.

Kate Middleton and Prince William's big date night to the Royal Film Performance came and went last night, and lucky for us, it offered a glimpse at the Duchess in another drop-dead gorgeous style! Although, it may look ever-so-slightly familiar, at least to the most loyal of royal watchers ...

Kate looked positively glam in her fitted, cream-colored Roland Mouret "Lombard" gown with a slit up the skirt. If you recall, the Duchess wore the '09 style in May 2012 to a Thirty Club dinner, so yup, it was fully recycled! Hey, even borderline vintage! Kidding. But this time around, she styled the dress in a whole different way ...

A thoughtful tribute to the late, great Nelson Mandela, the biopic Mandela: Long Walk to Freedom, premiered in London last night, and the shiniest stars in the firmament of celebrity were there to celebrate. This includes none other than the Duchess of Cambridge, Kate Middleton. 

Our lady Kate was wearing a chic white dress and a reasonably priced (though now totally sold out) necklace from Zara. She was also wearing a brilliant, if slightly dorky, grin on her face (JOURNALISM). What had Kate all agog? Why, easy access to one of Hollywood's sexiest men. We'd have a hard time staying so composed too -- and we are far from royal, though we do enjoy speaking of ourselves in the first personal plural. 

As we speak, Kate Middleton is going to be treated to something all new moms look forward to -- a date night to the movies with her husband, Prince William! Yup, lil' Prince George is being left with babysitters and his nanny as the royal couple enjoys a rare night out on the town together. Except this won't be your run-of-the-mill, "dinner and a movie" outing. Nope, it's actually -- yep, you guessed it -- for charity!

The Duke and Duchess will be the guests of honor at the Leicester Square UK premiere of Mandela: Long Walk to Freedom, this year's Royal Film Performance. Proceeds from the Royal Film night go to the Cinema and Television Benevolent Fund, which supports industry employees in times of hardship. (Cheers to that!) And this year's film is also set to raise money for the Nelson Mandela Children's Fund, which aims to create a better future for children in South Africa. Wonderful.

When it comes to style icons, I'm gonna go out on a limb here and say Kate Middleton is probably in my top 3. Granted, the girl has a royal glam squad that helps her look absolutely perfect almost every time she steps out into the public eye, but that doesn't mean we can't all take a few style tips from her.

With that said, 2013 has been a major year for Kate Middleton. The Duchess of Cambridge gave birth to Prince George, dyed her hair dark, and even changed stylists (whoa, buddy!).

In honor of the year that was, check out these 10 style lessons Kate Middleton taught us in 2013:

She's so down-to-earth and likeable that sometimes it's easy to forget she's royalty -- but Kate Middleton's beautiful tiara is the only reminder we need that she is, indeed, a princess.

This photo of her was snapped while she and Prince William were on their way to a diplomatic reception at Buckingham Palace hosted by the Queen. It's the first time she's been seen wearing a tiara since her wedding -- but man, does it suit her or what?

And duh, of course there are a few fun details about the headpiece -- which is most definitely the real deal.
