Lindsay Lohan debuted some seriously sexy vampire photos at celeb photographer Tyler Shields Presents Life is Not a Fairytale event on Saturday.
But instead of enjoying the party at the downtown Los Angeles gallery space, LiLo spent most of the night locked away in a private room:

"No one was expecting the paparazzi to rush the building like they did, so it wasn't surprising that Lindsay freaked," an event insider tells us. "But she wanted to be there for Tyler, so she stepped away into a private room while unwanted photogs were cleared from the building."
While Lindsay isolated herself from party guests, little sis Ali scoped out Shields' racy photos displayed on the walls.
"Lindsay resurfaced after the coast was clear and agreed to do a few pictures, but because there was such a commotion with her being there, the building security agreed to let her car come around back to let her leave in peace."
Whatever LiLo wants, LiLo gets.
Feeling more social at the same shindig...
Glee cast members, Kevin McHale and Jenna Ushkowitz cooling off at the Dyson Air Multiplier fan exhibit created by Shields. Brittany Snow, Shenae Grimes, and Emma Roberts also attended the fete in support of their photog friend.
Also in the mood to celebrate...
Eva Longoria, who ordered the Fatburger truck for the cast and crew of Desperate Housewives to celebrate their last day of filming.
"Eva and Felicity Huffman were the only women who ate the Fatburgers and both had regular, not turkey ," says our burger patrol source.
Also feeling hungry...
Cindy Crawford, Rande Gerber and their two kids, who celebrated Mother's Day at Caf Habana in Malibu, which Gerber part-owns.
"She looked flawless wearing practically no makeup and jeans and he looked so hot in jeans and a blue T-shirt," says our spy. "Rande was walking in and out of the kitchen, helping out the staff and was very friendly. A fan came up to Cindy outside the restaurant and she was polite, smiled and chatted for a bit."
Also at the restaurant was...
Kourtney Kardashian, Scott Disisck and baby Mason.
"They walked in right after Lamar got ejected from the Lakers game and didn't pay attention to the game at all," notes our eyewitness. "Mason is so adorable, he kept yelling out 'mom! mom! mommy!' Kourtney was feeding him, she and Scott were also on their cell phones a lot but looked happy."
Our extra pair of eyes also noted that the pair "stuck to iced tea and water" and "everyone in the restaurant was staring at them it was kind of awkward especially since Robert Duvall was also there--who is an actual star."
Also celebrating Mother's Day was single mom...
Christina Milian, who got Tei spa treatments at the On the Go Beauty by Joico event Saturday with her mom, sister and daughter.
Milian later spent Mother's Day dining at Chi Dynasty with her family, while fellow single hot mama...
Denise Richards, hosted Nintendo's nintendogs + cats 3D interactive event in Beverly Hills. Richards' two daughters were also in attendance to support their mom and, according to a puppy-friendly source, "played with the dogs all afternoon at the backyard event."
After being married to Charlie Sheen, we're sure Denise could handle any dog!
