Lily Collins looked every inch the perfect princess in a dainty strapless black and silver gown with sky high stilettos as she stepped onto the red-carpet at the Mirror Mirror premiere in Hollywood, on Saturday afternoon.

The raven-haired beauty was joined by dad Phil Collins and mom Jill Tavelman for the big premiere, where they also celebrated her 23rd birthday with a huge apple-shaped cake!

Meanwhile costar Armie Hammer, who plays Prince Alcott to Collins' Snow White, had a bit of a mishap on Saturday that kept him from attending the premiere!

The Social Network star accidentally missed his flight and arrived in LA looking exhausted, but just in time to attend the after party at the Roosevelt Hotel. Get some rest, Armie!

Could he be any cuter?

Model mama Miranda Kerr showed off her flawless figure in a pair of red skinny jeans paired with a striped top, cropped jean jacket and ballet flats as she proudly carried 14-month-old son Flynn to her Manhattan apartment in NYC after visiting the Children's Museum, on Saturday afternoon.

Is it just us, or is the little Kerr-Bloom looking more and more like papa Orlando every day?

The Australian model was named as the Global Ambassador for Earth Hour 2012 early this week, and she's vowed to teach a free yoga class if at least 500 videos are uploaded to her website offering ways to help the environment.

"This year I've made the commitment to reduce my footprint by offsetting all of my travel," the Victoria's Secret model confessed. "If we all adopt simple practices like recycling, switching to energy efficient lighting or paperless banking then we can make a difference together."

Looking chic in a black maxi dress that showed off her adorable baby bump, Victoria's Secret Angel Alessandra Ambrosio braved the dreary weather to take daughter Anja to the premiere of Mirror Mirror, in Hollywood on Saturday afternoon.

The adorable little girl donned a tiara for the special occasion, and they even met up with another supermodel mom!

Ambrosio shared a Twitpic from the theater, with the caption: "Having fun with Anja and my friend Gisele at the after party for the Mirror Mirror premiere!!!"

Adorbs!

Before playing chef at her grandmother Clara's birthday dinner last night, we spotted Rihanna stopping by Whole Foods in NYC to stock up on a few last-minute essentials.

As always, R&B starlet posted a ton of photos on her Twitter page over the course of the evening, and it looks like her grandparents are just as fun and easygoing as she is! Clara struck a few poses for RiRi in a baseball hat and sunglasses, and the trio appeared to be sipping on champagne.

While Rihanna's family is obviously super chill, that doesn't mean that her grandfather Lionel isn't puzzled by her constantly changing hairstyles! RiRi tweeted earlier, "My GranDad: Robyn how ya is get hair from red to cream to black??? Cuz ya don't carry wigs!!! Ya does wash it out?! ME: ROTFL. No words." LOL!

Jessica Alba and her baby daughter Haven Garner were snapped at a doctor's appointment in Santa Monica on Friday, and we still can't believe the tiny tot has Jess' mom's red hair!

And while the actress is busy with her two girls and The Honest Company, she recently hinted that she may have more children in the next few years. "I just have to feel it out," she told Latina mag after giving birth to her second daughter last year. "See how my 30s treat me. I just try to live in the moment."

Gisele Bundchen has posted several photos from her January trip to Kenya on her Facebook page, and she has also written a few blogs about her adventure.

The supermodel, who was named United Nations Environment Program Goodwill Ambassador in September of 2009, was at the David Sheldrick Wildlife Sanctuary as part of her first official visit to Africa.

The Brazilian beauty wrote on her Facebook page, "When I went to Africa I discovered that elephants are one of the smartest and most complex mammals on earth. If we don’t protect them, they can be extinguished." We're thinking she means extinct, but at least her heart is in the right place!

So what about the little one? "I met a baby elephant who was only two months old and had just arrived at the sanctuary. He touched my heart. He was shy, scared, and still traumatized from losing his mother. He was not ready to be playful with the other members of his adopted herd. He was so sweet, looking for a little love and one of my friends hugged his trunk. It was [amazing] to meet the baby elephants." Awww!

La Toya Jackson, Brooke Mueller, Kyle Richards and Nicky Hilton got together to celebrate Kathy Hilton's birthday at Il Cielo in Beverly Hills yesterday, and despite the gloomy weather, the ladies appeared to have a great time catching up.

Kathy already celebrated her 53rd bday at Mr. Chow and Dan Tana's earlier this week, and we're guessing the party is going to keep on going throughout the weekend!

The Kardashians (well, most of them!) jetted to Las Vegas to celebrate Rob's 25th birthday, and it looks like the family had a blast at 1 Oak at the Mirage Hotel. Kourtney wasn't able to attend as she was doing a live QVC event, and we aren't sure why Khloe wasn't able to make it, but her birthday tweets definitely seemed to make up for her absence.

Kim tweeted a half dozen shots as the evening went on, and while Kylie, 14, and Kendall, 16, weren't allowed to party at the club, they still got all dolled up for dinner at Stack Restaurant & Bar.

While the Kardashians could have kept going, it looks like they put an end to the festivities pretty early. Well, for Vegas, anyway! This morning Kim tweeted, "3am flight back home! What a fun night!"
