Angel McCord, Rachel McCord and Annalynne McCord blow kisses at Pure Nightclub.

Last night, AnnaLynne McCord of the hit television series “90210” kicked off the Halloween weekend by hosting a night of haunted seduction at Pure Nightclub inside Caesars Palace. The Hollywood starlet arrived at the mega-club along with her sisters Angel and Rachel McCord. In full Halloween spirit, the trio showed off their stunning Victorian costumes as they posed for the cameras. While on the red carpet, AnnaLynne introduced herself as Marie Antoinette for the night and even pointed out that she added a little personal flair to her costume by sewing on additional details such as the ribbons on her heels.

After posing for photos, the sisters along with their entourage were escorted inside to the VIP area located on Pure’s main stage where they immediately became the center of attention. Female admirers flocked their table in hopes to meet the girls. All three McCord sisters graciously met with fans and took photos with them. As a double celebration, the evening also served as Rachel’s 23rd birthday bash. In true Vegas fashion, the youngest McCord was presented with a stunning Halloween-themed birthday cake in honor of her special day. AnnaLynne and Angel joined their little sister as she made a wish and blew out her candles while the whole club cheered her on.

Later in the evening, the party really got started as the contest for “Best Costume” began with AnnaLynne as the lead judge. As a true fan of the spooktacular holiday, the gorgeous actress got really into the contest as she thought some of the costumes “were so crazy!” After multiple rounds of judging, the blonde beauty along with help from the crowd picked the top three contestants and declared the winners: first place was awarded to the “Hangover Guy,” second place went to “Iron Man” also known as AnnaLynne’s favorite and third place went to “Swamp Man.” Pure Nightclub gave away a total of $10,000 to the winners.

Once the costume contest winners were announced, AnnaLynne rejoined her sisters to party therest of the night away. While Angel and Rachel sipped on champagne, AnnaLynne opted to drink water all evening. But that didn’t stop the energetic actress from enjoying the atmosphere of the club and dancing with her sisters.

The McCord sisters started the evening with dinner at Social House inside Crystals at CityCenter where they indulged and dined on Executive Chef Peter Woo’s delicious pan-Asian cuisine.
