Olivia Newton-John unveils Madame Tussauds wax figure in Las Vegas

Fans of singer Olivia Newton-John who are hopelessly devoted to the singer can now catch her live in Las Vegas -- where her new wax figure is on display.

The Grammy Award winner did a double-take in Sin City as she stood next to her freshly unveiled Madame Tussauds wax figure at the Flamingo Hotel. The figure will remain in Las Vegas for a week before being shipped to Los Angeles.

“It’s very strange, it’s very bizarre,” Newton-John said. “Um, it’s like before and after.”

The wax figure is a replica of her character Sandy from the cult classic 1970’s film, "Grease." The likeness took hundreds of hours to make and cost $300,000.

“This character will always live on,” Newton-John said. “It’s given people so much pleasure over the years. That’s a really good feeling.”

The wax figure comes in the midst of a big comeback for the internationally-acclaimed singer and actress.

Newton-John's new show, "Summer Nights," at the legendary Flamingo Hotel is a hit, attracting fans of all ages.

“It’s a wonderful experience,” Newton-John said. “I’m having a great time here at the Flamingo. Summer Night’s is so much fun.”

Newton-John tells FoxNews.com that she’s also hitting the studio to record new music, including collaborations with other artists -- but she won't say with whom.

“I won’t tell you yet,” Newton-John said. “But I will tell you when the time is right.”
