Katy Perry may be in the middle of a world tour, but that isn't stopping her from taking a day to relax -- and pose for a few bikini snapshots!

On Monday the 30-year-old singer explored Hayman Island off the coast of Australia, and she uploaded the above picture to Instagram. KP is set to perform in Melbourne today and tomorrow, and later this week she'll kick off the first of four shows in Sydney. And she'll be down under for a while! She has 13 more shows between now and December 20, and then she'll have a two-month break before hitting the road for the European leg of her Prismatic tour.

And she wasn't the only one who showed some skin on social media yesterday! Tara Reid took to her Twitter to post a bikini snap from Hawaii, but it wasn't nearly as sexy as Katy's:

Oh that dirty dawg!

Bad boy Tyga was caught spending some time with a Kim Kardashian lookalike on Monday. The two were spottted outside the rapper's matte, fire-engine red Range Rover together -- so there's really no denying it!

We wonder what his rumored teenaged lady love Kylie Jenner thinks about this?!

Umm if Tyga wanted to keep things on the DL -- he probably shouldn't have worn that loud ensemble! It's Michael Jackson-meets-Justin Bieber and we are not feeling it!

Tyga was allegedly dating Kylie -- the two went to Europe together -- but last week he was spotted on the red carpet with Drake's ex Dollicia Bryan. And now he's been spotted walking with an unidentified woman (who looks just like Kim!). After being caught, Blac Chyna's ex sent the faux Kim packing back to her home and he drove off.

We can't keep Tyga's love life straight -- and it looks like he can't either!

Khloe, Kourtney, Kylie and Kendall Jenner got all decked out in their winter best to film a girls-only dinner at Kate Mantilini in Topanga Canyon at Kate Mantilini on Monday night. Of course it wouldn't be a Kardashian/Jenner dinner if it wasn't being filmed!

If a tree falls in the woods and no one is around to hear it -- does it make a sound? We don't know! But if there's a Kardashian dinner and no one is around to film it -- we know it definitely doesn't count!

For the dinner party, Khloe opted for a black leather jacket, jeans and knee high boots. Kendall donned wax skinnies, a leather jacket and a tan shirt. Pregnant Kourtney opted for an all black ensemble topped off with a chic winter white coat. Goth girl Kylie donned an all-black ensemble -- and opted for her new favorite accessory -- her oversized, puffy lips! Seriously -- those things look they could be a parade float! And we couldn't help but notice Kylie is wearing her favorite Cartier bracelets -- to be precise she is wearing six of them! Each one is around $7,000 -- which means she is wearing $42K worth of bracelets. Kris Jenner really knows how to instill humility in her daughters!

This boy bander is pissed!

One Direction's Zayn Malik is fuming mad over Matt Lauer's suggestion that drug abuse was the reason he missed a promotional appearance on The Today Show with the rest of bandmates, and he wants to make it clear he was simply under the weather!

"I'm really angry and upset by what was said on The Today Show. I was really ill at the weekend. That's why I couldn't fly to America," he vented to The Sun.

"Zayn was taken ill after recording the Band Aid single at the weekend and was unfortunately not well enough to fly to the USA yesterday. He will join the band for promotion for the new album as soon as he possibly can," a rep for the group said at the time.

We don't blame him for being outraged!

Kristen Stewart jetted out of Los Angeles International Airport on Monday afternoon, and after pal Riley Keough's bachelorette party over the weekend in San Luis Obispo, the 24-year-old actress is back to the grind.

K. Stew is currently campaigning for an Oscar for her role in Still Alice, and production recently wrapped on her upcoming film Equals, but we have a feeling she might have some re-shoots for the sci-fi flick. She stars opposite Nicholas Hoult in the film, and though there were rumors that the two were hooking up, it doesn't seem like that was the case. Either that, or it totally fizzled out!

K. Stew and her gal pals headed up to SLO last weekend, and though Keough and fiance Ben Smith-Petersen have only been engaged for three months, it seems like a wedding might just around the corner for the couple. The group of girls stayed at the Madonna Inn, and they enjoyed brunch together and a night on the town. Even though she looks a bit grumpy here, it looks like a little weekend getaway was the perfect pre-Awards season stress reliever for the former Twilight starlet.

Nathaniel Wood/NY Times

This is probably the most asinine interview we've ever read, and while we're trying to remind ourselves that these are two teenagers attempting to share the wisdom they've gleaned in their short lives, it still doesn't make it much better.

Will and Jada Pinkett Smith's kids, Willow, 14, and Jaden, 16, are profiled in a new article in the New York Times, and while the publication doesn't straight up make fun of them, the quotes in the piece speak for themselves.

The two started off the interview by revealing that they are reading quantum physics and ancient texts, and they then jumped into their music and how fame affected them at an early age. "Honestly, we’re just trying to make music that we think is cool," Jaden eloquently states. "We don’t think a lot of the music out there is that cool. So we make our own music."

Willow added, "That’s what I do with novels. There’re no novels that I like to read so I write my own novels, and then I read them again, and it’s the best thing." The two talk about collaborating ("Me and Jaden just figured out that our voices sound like chocolate together. As good as chocolate tastes, it sounds that good," Willow says), and they also discuss how art is about "shocking people."

And not only do these two have a majorly inflated sense of self, but they weigh in on why they think school is totally pointless. The two used to attend the New Village Leadership Academy, which focused on nontraditional methods of education used in Scientology, but they haven't been in a formal classroom environment for years. Willow has been home-schooled since she was 12, and Jaden dropped out prior to that.

According to Jaden:

"Here’s the deal: School is not authentic because it ends. It’s not true, it’s not real. Our learning will never end. The school that we go to every single morning, we will continue to go to…Kids who go to normal school are so teenagery, so angsty. You never learn anything in school. Think about how many car accidents happen every day. Driver’s ed? What’s up? I still haven’t been to driver’s ed because if everybody I know has been in an accident, I can’t see how driver’s ed is really helping them out."

Willow added, "They never want to do anything, they’re so tired ... I went to school for one year. It was the best experience but the worst experience. The best experience because I was, like, 'Oh, now I know why kids are so depressed.' But it was the worst experience because I was depressed."

"I have a goal to be just the most craziest person of all time," Jaden proclaims. "And when I say craziest, I mean, like, I want to do like Olympic-level things. I want to be the most durable person on the planet." He's off to a great start, because at this point he's making Amanda Bynes seem totally sane...

Big Pictures Australia

Angelina Jolie looked gorgeous in grey at a photo call for her latest directorial effort, Unbroken, and she took a moment to pose with the film's stars at the Sydney Harbor in Australia.

The 39-year-old actress then spoke at Sydney's Opera House for a press conference, and she opened up a little bit about her personal life. Jolie revealed that she and husband Brad Pitt were apart for several months while she was filming the flick, and that they kept in touch the old-fashioned way!

"We wrote letters back and forth, 1940s-style," she said. She then gushed about how supportive her hubby was during the project, and said, "[Unbroken] is an epic about the human spirit, so I think certainly in knowing, less about the technical aspect of shooting a war film, but more what I know of him [Brad] as a man and living with this great man and seeing the choices he makes with our family, our children, the way he treats me and the values he holds and learning from my sons. These are things I think I brought to the film that I understand about men and what I love about men, and what I think I'd want our generation to be reminded of."

Kim Kardashian appeared on the Australian TV show The Project today, and the reality star dished all about her infamous Paper Magazine shoot, in which she bared her naked ass (and boobs and vag) for the publication.

Kim started off by saying, "I looked back at a clip of Keeping Up with the Kardashians last season and I was really heavily pregnant, I was about eight months pregnant, and I looked at my sisters and said, ‘You guys, when I feel like I have my body back, I’m doing a nude shoot.'"

"I was so honored and excited to work with [photographer Jean-Paul Goude] because he is a legend, and for me that was something I wanted to do to make myself feel confident," she continued. "As a role model I'm not saying anyone else should do that, but for me it was an art project and it taught me to do what you want to do. I'm never one to preach, but I felt really positive and really good about myself. I love the photos, I did it for me, I hope other people like them."

Show host Rove McManus told Kim he loved the raunchy pics, and then asked, "Can you actually balance a champagne glass on your derriere, or was it all Photoshopped?" Kim insists it was real and said with a laugh, "My back hurt for about a week after that shoot. I used muscles -- [Goude] has an art of posing you and it was definitely not comfortable."

Of course, McManus was so interested in this, he then asked Kim to either do it again or teach him how to do it, and Kardashian happily agreed to help him out, but he just couldn't get it right. "You don't have as big a butt as I do, so..."
