What a mix-up!

Anne Hathaway surprised fashion fans when she chose a pale pink Prada gown over the Valentino creation she was set to walk the Oscars red carpet in, and apparently the last minute change was executed out of fear that co-star Amanda Seyfried's Alexander McQueen dress would look too similar to her own.

Valentino's camp sent out a press release Sunday just hours before red carpet arrivals began that stated the Les Miserables star would be wearing "a pink embroidered tulle illusion gown", so clearly the designer wasn't kept in the loop about her style switcheroo!

Presenter Jennifer Aniston was expected to wear a "nude embroidered silk tulle dress" also by Valentino, but many believe the A-list actress switched to her red strapless number after catching wind of Hathaway's similar style.

Basically, Anne changed her dress choice because of Amanda, and Jen changed her dress choice because of Anne!

At least all three lovely ladies avoided a matching fashion faux pas!

She's never been one to shy away from controversy, that's for sure!

Madonna joined Instagram mere weeks ago, but already the Instagram Team is sending her letters requesting she tone down her sexy snapshots!

Clearly not embarassed about the slap on the wrist, Madge decided to upload the letter in full to her account, followed by a picture of herself in a black wig and cleavage-baring green leather dress. Yikes!

Some of the things on their no-no list? Sharing photos that aren't your own, sharing photos that show nudity or mature content, sharing photos of illegal content, and sharing photos that attack individuals or groups.

We think we know which violations she's guilty of...

It could have been her sweaty cleavage shot, or it could have been her booty pic, but something has made the app administrators angry!

Kim Kardashian covers the latest issue of Cosmopolitan, and while you can't really tell that she's pregnant in this photos, they were taken just two months ago, so she definitely knew she was expecting!

And speaking of babies, Kim says she once judged her sister Kourtney for getting knocked up before walking down the aisle. "I was like, ‘You're not married! How could you do this?' I was really firm and strict," Kim told the mag. "But she was like, ‘Marriage isn't what I want.' And later, I realized she had a better family life than I did."

Marriage is "something I know that we both want in our future," Kardashian said of baby daddy Kanye West. "But I don't have this sense of urgency about it." When asked about Yeezy, she added, "I have this best friend who understands me and helps me through all my tough experiences, and vice versa, you know? It just feels like this is it for me."

"I've always said that I wanted kids," she continued. "But I don't think I ever would have been ready until now. Sometimes you're just not ready. A person could have it all, and you're not ready for it all. But this is where I probably always should have been."

She's so pretty in pink!

Heidi Klum and boyfriend Martin Kristen took the model's children Henry, Johan, and Lou out for a Starbucks run in Brentwood the other day, and the whole gang seemed to be in a great mood as they grabbed their java.

The former bodyguard seems to be such a natural with kids! The Project Runway host has admitted that's one of the reasons she fell for him in the first place!

The German stunner looked sporty in a bright fuschia sweatshirt and matching sneakers. We wonder if these wares are part of her upcoming New Balance collaboration?

The mother-of-four is partnering with the athletic company for the third time on a "versatile active wear collection", which will include skinny tights, capri pants racer back tanks, shorts, and hoodies.

"I live an active lifestyle and love running around whether it's outside on the streets of New York City or in the canyons with my dogs. I've created pieces in my collection that are functional and flattering with a fashionable twist. I want women to feel their best and look good in their clothes even when they are working up a sweat," Klum said in a statement.

She's one good looking walking advertisement!

Chris Brown chatted with The Mirror about his 2009 assault on Rihanna, and though he says it's the biggest mistake of his life, he adds that they've moved on and that Ri still "loves him" and has "forgiven" him.

"That night was the deepest regret of my life, the biggest mistake," Brown said. "Sometimes you fight with the one you love and things get said, stuff spirals."

While the couple have broken up and reconciled so many times we've lost track, it does seem like they've put the incident behind them, but on Sunday Oscar host Seth MacFarlane made sure to remind everyone of their violent brawl.

MacFarlane introduced Django Unchained as "the story of a man fighting to get back his woman, who's been subjected to unthinkable violence, or as Chris Brown and Rihanna call it, a date movie."

Chris hasn't spoken out about the Family Guy creator's remark, but much like the Hulk, this is one guy you don't want to see lose his temper!

Like father, like son!

Nick Lachey poses with his 5-month-old baby boy Camden on the cover of his new album of lullabies, and we can't believe how much the little cutie looks like his daddy!

Titled "A Father's Lullaby", the album features four songs written by the former boy bander, which were inspired by his own journey into fatherhood.

It will be available on iTunes March 13, and in stores starting in April!

Bedtime songs aren't the only thing he's focusing on, though!

The singer will release a new album titled "2.0" with his 98 Degrees bandmates in May.

Too cute!

Hilary Duff is currently basking in the sun with her family in Hawaii, but before they left Los Angeles we spotted the former Disney starlet and her adorable son out and about in the valley.

Hilary and hubby Mike Comrie got married in August 2012 in Santa Barbara, and last March the couple welcomed their first child, Luca. So is this is a baby making trip? Not quite yet. While Hil previously told Access Hollywood that the couple were considering having a second child, she added that they would probably wait until he was two or three.

Plus, she's got that new 20th Century Fox show in development, so she's definitely busy these days! Sounds like a trip out of town is just what she needs!

Peter Parker, is that you?
