Seriously -- we didn't think we could possibly love Kate Middleton any more than we already did -- and then this photo of her planting a tree with children comes out. Now our hearts explode a bit more.

On Thursday, the Duke and Duchess of Cambridge visited the National Arboretum, the site of a bushfire in 2003. During the step, Kate visited with local children, planted an oak Tree and did it all while looking absolutely fabulous.

Today is the last day of the the Royals' three-week tour of Australia and New Zealand. Currently, the Brits are making several stops through the Australian capital of Canberra. Say it ain't so!

For the tree-planting, the 32-year-old showed off her green thumb outwardly with an emerald green Catherine Walker coat dress.

The Duke and Duchess had all eyes on them when they later made a stop at the Parliament House, where Prince William made a speech reflecting on their trip with their son Prince George.

"Reluctantly, Catherine, George and I leave Australia tomorrow," William said. "Thank you for the warmth and generosity that has been shown to us during our visit. We go away with wonderful memories, and George goes away with his cuddly wombat, which he has taken to chewing so lovingly. We greatly look forward to coming back. And when we do return, it will be to marvel again at all that Australia is, and will yet become."

Oh my gosh -- we love Prince William's British wit! But what we will miss most about the lack of daily photos of the young family -- that adorable Prince George!

We already got a peek at some of the crazy characters Katy Perry plays in her new music video for "Birthday," and now the full version has hit the web!

Katy plays Goldie Dancer, Yosef Shulem, Kriss The Clown, Ace The Animal Trainer and Princess Mandee, and the hilarious video starts off by saying, "In April, 2014, Katy Perry attended 5 birthday parties…Only no one knew it was her." Katy proceeds to prank all sorts of partygoers in her various disguises, and we're not sure how she was able to pull this off, but it might just be her best work yet!

Katy tweeted the video and wrote, "GUYS, PREPARE YOURSELVES cuz it’s time to bring out the big balloons and #MakeItLikeYourBirthday!"

Which birthday entertainer is your fav?

Justin Bieber's new protege Madison Beer grabbed lunch at the Ivy in Los Angeles on Wednesday, and after shopping at Kitson X17online caught up with the 15-year-old singer. Miss Beer chatted all about working with the Biebs and what we can expect from their recent collaboration, and not only is she adorable, but she was so sweet and humble!

Madison confirmed that the two did a duet and recorded a few other songs together, and Bieber even wrote a pair of tunes for her. "I'm excited for everyone to hear them," she gushed, adding that Justin is a "very big influence" on her music. "I am a Belieber," she said with a smile.

And seeing as Selena Gomez visited the studio while Bieber and Beer were cranking out some tunes, it doesn't seem like there's any sort of awkward tension with them. Still, we're sure her stunning looks had something to do with Bieber taking her under his wing...

Even in a casual outfit with minimal makeup, Kendall Jenner is gorgeous! Guess that's why she's getting paid the big bucks to model ... and with Chanel and Marc Jacobs runway shows under her belt, clearly she's set to have a very successful career!

On Thursday morning Kendall jetted out of Los Angeles International Airport, and while she was waiting for her flight she tweeted, "rise and shine love bugs! y'all make me happy ... just so you know."

Wonder where she's headed? We're thinking it's for a modeling gig ... or perhaps she's traveling to Colombia to rekindle things with One Direction hottie Harry Styles? We'll find out soon enough...

Work it out, girl!

Reese Witherspoon is working out yet again, hitting up her favorite spot Burn 60 with a friend in Brentwood on Wednesday. The 38-year-old has been on a health kick for the the past year, constantly spotted working out her fit form. But yesterday the actress had not one, but two work outs. Color us impressed!

For Wednesday's workout, the Oscar winner went for a punches of color -- with a pink tank, pink yoga mat and pink shoes.

Amazingly enough, just after leaving her rigorous 60-minute class, Reese and her friend went for a run around a nearby golf course. The bubbly blonde's really pushing herself to the limit!

The actress must be gearing up for her next film role, the action-comedy called Don't Mess With Texas, in which she stars opposite Sofia Vergara. Reese definitely has the right idea -- if we were starring in a movie with the Latin beauty we'd be working out like maniacs too!

Hot Grandma alert!

On Wednesday Goldie Hawn and a pal went for a walk in their Los Angeles neigborhood, and we still can't believe that Goldie is nearly 7 decades old!

"My exercise routine is really varied ... I do try to do some form of exercise four days a week," Goldie told Prevention magazine last year when asked about her fitness regimen. "At home in California, I'll bike up the mountain, or I'll do Pilates or spin. And I do eat a lot of greens. I eat healthy, but I'm not a vegetarian."

We think she looks fantastic!

Move over Kate, William and George -- we've got an new threesome stealing headlines down under! The three gorgeous stars of The Other Woman, Cameron Diaz, Leslie Mann and Kate Upton all got gussied up for the comedy's photocall in Sydney, Australia on Thursday. And damn, are they looking hot!

While we are of course big fans of black and white -- all three ladies seem to be coordinating. They're kind of like a more chic Destiny's Child. Just further proof that the '90s are back!

Their film revolves around Carly (Cameron), who discovers her too-perfect boyfriend is actually married to Kate (Leslie). Carly and Kate soon strike up a friendship and upon realizing their mutual man is cheating on with them with yet another woman (Kate) -- all three spurned women team up to plot mutual revenge on the three-timer.

The Other Woman hits theaters on Friday, April 25.

Harry Styles got in a chauffeured car and headed to Los Angeles International Airport yesterday afternoon, and the 19-year-old singer was en route to Colombia, where One Direction will be kicking off their Where We Are stadium tour on Friday.

Though Harry was able to fly under the radar in LA, apparently there were hoards of fangirls waiting for him and the other 1D boys at the airport in South America. Hey, they're used to it by now, and things are going to blow up even more once the tour gets underway. "It's starting really soon," Harry tweeted after landing last night.

But what's this about Harry leaving 1D?! Apparently One Republic singer/songwriter Ryan Tedder worked with Harry on a "top secret project," and though one of the UK tabloids jumped to conclusions and suggested that Harry is quitting the band, it seems like Tedder's words simply got twisted around. "Oh my God, I have no idea," he replied when asked if Harry was leaving the group. "I've never had any conversations with him or any of them regarding that."

Whew!
