The cast of Glee came out to celebrate their co-star Cory Monteith's 30th birthday Friday night. The gang all headed to the "after-party" after first gathering for the show's wrap party in Beverly Hills.

Pal Lily Collins turned out as well and everyone was in for a little birthday surprise when the cake was brought out. Click through to see the NSFW creation ...

It's not hard to see why Lily Collins made People mag's "Most Beautiful" list this year, because the Mirror Mirror star is definitely one of the fairest of them all in Tinseltown!

The stunning brunette, and daughter of musician Phil Collins, showed off her sweet and sexy side in an edgy motorcycle jacket, paired with cute flowery skinny jeans and gold ballet flats while out to dinner in Beverly Hills, on Monday night.

The 23-year-old budding actress said of making People's annual list this year, “The first person I looked at and thinking they were so, so beautiful…cheesy as it is, but my mom. She was always about minimal makeup and just embracing who you are, and the quirky things that make you different and make you beautiful.”

Lily added, “That’s the mantra I live by now.”

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!

Hunky heartthrob Zac Efron and Mirror Mirror's Snow White, Lily Collins, shared a romantic dinner at Soho House West Hollywood on Valentine's Day and X17online has the EXCLUSIVE photos!

This isn't the first time we've spotted the pair together ... Zac, 24, and Lily, 22, enjoyed a night out at STK steakhouse on Feb. 4.

There's still been no official word as to whether the two are dating, but spending Valentine's Day together? It must be love!

Looks like Zac Efron has a new girl! The 24-year-old hunk took new "it" girl Lily Collins on a date Saturday night at LA's STK steakhouse.

We spotted the two trying to slip out the back door and while we just barely caught Zac slipping into a chauffeured SUV, we got a surprised-looking Lily as she made her way to the same car.

Collins, who turns 23 next month, will appear in her biggest role to date as Snow White in the upcoming Mirror Mirror, while Zac has three big films coming out this year -- The Paperboy, The Lucky One and another yet-untitled movie.

The pair were trying to avoid attention, according to our photographers at the restaurant last night: "Zac literally ran to the car and jumped in, leaving Lily behind. But Lily kept her cool and took her time. She wasn't as worried about not being seen by us. She took her time. She probably didn't want to trip in her heels!"

Collins was recently linked to Taylor Lautner who, according to reports, is back together with his high school sweetheart. Zac was rumored to be dating Taylor Swift just a few weeks ago, but most sources shot down those rumors as false.

Maybe Lily is Zac's REAL girlfriend ... seems like a relationship he wants to protect!

Lily Collins has been cast as Snow White in Relativity Media's upcoming live action film based on the classic Brothers Grimm fairytale.

Collins will star opposite Julia Roberts and Armie Hammer, and production is set to begin next month, with a planned release date of June 2012. Roberts will play the evil queen, while Social Network hottie Hammer will play the prince. Saoirse Ronan was originally rumored to play the highly coveted role of Snow White, but it seems as though Collins was able to convince casting directors that she is the fairest of them all.
