Aubrey O'Day Is 'Going For Blood' This Halloween

Aubrey O'Day is ready to deliver this Halloween season. With dogs Ginger and Mary Ann by her side, she is certain that her top-secret costume will have everyone buzzing this weekend, and she's ready to challenge dress-up superstars Seal and Heidi Klum (who host an annual celeb-filled party for the holiday) to a costume competition.

"We're gonna kill it for Halloween," the former Danity Kane singer teased MTV News. "I don't think anyone's ready!"

When pressed for more details about her look, O'Day decided to not let the cat out of the bag. She wants to keep her fans guessing until the big day. "I don't know if I should give it up, but my dogs and I will be doing something together again."

The reality starlet and her pups have a history of dressing up together for Halloween. "Two years ago we were the Little Mermaid and Sebastian," she said. "Last year, I had my new dog, so we were Batman, Robin and Cat Woman. And this year we're going for blood. We're about to beat Heidi Klum and Seal."

Previously, O'Day admitted to being one of the many celebs who are considering dressing up as the pickle-loving star of the "Jersey Shore." "Snooki's my favorite," she said. "I love her. ... The hairspray! The bump!"
