Heartthrob Cory Monteith, who plays the role of Finn on the hit U.S. series 'Glee', has urged his Twitter followers to help save a Canadian building from being "turned into condos" by signing a petition.

He took to his official social networking page last night (January 13) and asked his 1.4 million fans to add their signatures to a document that is trying to stop the conversion from happening:

"the @waldorfhotel, a cultural bastion for the city of Vancouver, is in imminent danger of being turned into condos. Sign the petition!"

He then posted the link and added: "I know everyone is watching the globes, but this place is really special and Vancouver has enough condominiums. #savethewaldorf"

His girlfriend and 'Glee' co-star, Lea Michele, attended the Golden Globes ceremony yesterday evening although he wasn't with her for the event.
