On Tuesday evening an impeccably dressed Gwyneth Paltrow attended Meet The Developer at the Apple Store in SoHo, and she chatted about her iPhone app Goop City Guides, which features her favorite places in New York, Los Angeles and London.

The app may be $3.99, but we're wondering if we can get in or even afford to eat at her fav metro hotspots. According to her website, the app "is filled with all of the much-loved and under-the-radar places, along with classic favorites," so we have some hope!

Gwyn also chatted about her favorite apps, and revealed that Pinterest, Flight Tracker and iTranslate are her top three. Who knew?

We can't feel that sorry for People's World's Most Beautiful Woman, though!

Gwyneth Paltrow ditched her undies when she walked the red carpet in a sheer Antonio Berardi dress at the Iron Man 3 premiere, and the actress confessed she was "humiliated" at the all the bad press her ensemble received during an appearance on Ellen today.

"I kind of had a disaster. I was doing a show and I changed there and I went 'I couldn't wear underwear.' I don't think I can tell this story on TV. Well, let's just say everyone went scrambling for a razor," she joked to the talk show host.

TMI!

She may have been all glammed up last night at the Iron Man 3 premiere and she was just named the world's most beautiful woman by People magazine, but Gwyneth Paltrow stepped out without makeup on Thursday morning and hid her face!

X17 photographers snapped the Oscar-winning Gooper leaving a meeting at an organization in Santa Monica that connects celeb philanthropists with non-profit organizations ... such a do gooder, this one! Gwyn wore baggy jeans, a sweatshirt and dark shades, and while she still looks better than most of us, why is she looking so frumpy the day after wearing a totally see through dress and Louboutins? Maybe she doesn't think she deserves the title?

When asked about her People cover, the Gwyn told The Associated Press, "It's funny, these things, because it's like obviously not true. But it's very sweet to be named that. Because I mean you can't say that, you know! But it's been wonderful. It's been very wonderful. And as my friend said, it's so nice that someone who has kids and is a mom and is not like 21 is named that. It's really an honor."

The most beautiful woman in the world certainly knows how to steal the show!

On Wednesday evening Gwyneth Paltrow attended the Hollywood premiere of Iron Man 3 at the El Capitan Theatre, and all eyes were on her stunning figure, which was on full display in a sheer paneled Antonio Berardi dress.

"It's very see-through," Gwynnie told E! News. "I just thought it was really beautiful and it sort of has a superhero thing happening."

Of course, Iron Man himself was there too:

We would have to agree!

Gwyneth Paltrow has been crowned World's Most Beautiful Woman by People magazine, and the actress admits she was a little shocked by the flattering title!

"Around the house, I'm in jeans and a t-shirt. I don't really wear make-up. That's what they're used to. And Chris will make a joke about it. If I've gotten fully dressed up, he'll be like, 'Oh, wow! You're Gwyneth Paltrow!' Because he's used used to seeing me in like baggy shorts and frizzy hair," she confessed to the mag.

The Iron Man star is not just a pretty face, either! The blonde beauty is known for her amazing physique, but the star insists her adherence to a fitness regime didn't come naturally at first.

"When I first started, I thought, 'I'll never be good at this. This is a nightmare!' But now it's like brushing my teeth, I just do it. It makes me look younger and feel strong," she added.

Others Hollywood starlets that made the list include Kerry Washington and Jennifer Lawrence.

We absolutely love GP!

Yup, Gwyneth Paltrow is still promoting her new cookbook!

The 40-year-old actress/author was snapped en route to yet another signing in New York City on Wednesday, and we're not sure who's been styling her for these things, but her fashion has been really sub-par lately!

And speaking of fashion and beauty, Gwyneth covers the May issue of Harper's Bazaar and chats about different things she's tried out over the years. "I use organic [beauty] products, but I get lasers. It's what makes life interesting, finding the balance between cigarettes and tofu," she says. "I've probably tried everything ... I would be scared to go under the knife, but you know, talk to me when I'm 50. I'll try anything. Except I won’t do Botox again, because I looked crazy."

Wait, back up a second -- cigarettes?! "My one light American Spirit that I smoke once a week, on Saturday night," she said when asked about her guilty pleasures.

While she's busy attending book signings for It's All Good: Delicious, Easy Recipes that Will Make You Look Good and Feel Great, she's not sure what she wants to do next with her life. She said, "I'm at quite a pivotal point: Do I want to go back more into films? Do I want another child? Do I want to move back to the States?" she says. "You can call me a lot of things, but you can't call me complacent!"

We had no idea Pepper Potts got to wear Iron Man's suit for the third installment of the film franchise!

Yet another clip from Iron Man 3 hit the web this week, and in it we see Gwyneth Paltrow's character apparently saving Tony Stark from a certain fate.

Stark prepares to battle it out against the Mandarin, played by Ben Kingsley. The film hits theaters on May 3.

Gwyneth Paltrow covers the April 2013 issue of Self Magazine, and the actress chats about her diet and how going gluten-free has made her less irritated about everything. Funny, because when we cut the carbs, we get decidedly more grumpy...

On going g-free, Gwynnie says, “You feel lighter and your emotions get smoother. [Before the diet, I] had a lot of unexpressed anger. I made everyone else’s feelings more important than my own. I’d suck it up and then be alone in my car yelling at traffic or fighting with hangers in my closet when they got stuck together.”

Of course, Gwyn is currently promoting her new cookbook, It's All Good: Delicious, Easy Recipes that Will Make You Look Good and Feel Great, so of course she's trying to convince us to buy it to follow her footsteps when it comes eating healthy.

She explains that she decided to make a change after hitting a low point a few years ago. “I had to sing at awards shows, which was fun but stressful," she says. "I’d have a Guinness and a beta-blocker every time. I also was constantly getting on airplanes, trying to knock myself out with sleeping pills and wine, waking up, trying to sweat it out with exercise and a steam, and then working really hard all day. Eventually, I had a panic attack. My body was like, ‘What is happening?’”

"My doctor, Alejandro Junger, recommended that I cut out basically everything: dairy, sugar, gluten, anything processed. I was like, 'What the f*ck am I going to eat now?'" she says. "That's why I made the book: to stop eating brown rice out of the fridge because I didn't know what else to eat -- it was demoralizing.

"I probably eat this way two or three times a year for three weeks at a time. Past that, I'm not willing to make the sacrifice. Life is about balance," she continues. "It's good to work in healthy food, whether it's five days a week or five meals a week. And if you're going to do it, it should be awesome food you're psyched to make. But never cut out the brownies or the wine."
