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!
Collins says she was injured on set during one of the sword fighting scenes, telling Stella magazine, "There were 150 sword moves and Armie smacked me several times. No blood was drawn, but I was so bruised. It doesn't matter how much padding you wear, those swords are lethal."
