London: `High School Musical` star Zac Efron is furious with his friends who trashed his garden while he was away filming movies.
The 23-year-old actor, who was away from Los Angeles for several months for the shooting of `The Paperboy` and `Heartland`, had permitted his friends to use his pool at his house.
But he soon regretted his decision when his parents visited his home and discovered the property in a huge mess, reported Contactmusic.
They instantly sent him a message to say, "The place looks like a bomb hit it."
"His pals had turned his backyard into a filthy mess filled with food wrappers, cans, bottles, towels, paper cups etc," said a source.
Efron immediately took action and his friends are no longer allowed to relax in his garden while he is not there.
"Zac was totally upset, immediately ordered the locks on his gate changed - then phoned his buddies and told them their pool privileges are revoked," added the source.
