Weed fiend Miley Cyrus said, "I DON'T" to drugs — so she could say "I DO" to Liam Hemsworth in a super-secret wedding!
RadarOnline.com has exclusively learned the "Wrecking Ball" singer, 23, and Hemsworth, 26, tied the knot at the Down Under home of his big brother, Thor star Chris — and her dad, Billy Ray Cyrus, officiated.
And while some brides like to diet before the big day, "shredding for the wedding," "Miley quit weed for Liam," said an insider.
"She went cold turkey two months ago. The first week was the most difficult, but she got through it."
In a blockbuster, exclusive in January 2015, The National ENQUIRER exposed wild child Cyrus's drug use from inside her drug den — a room in her California mansion where she binged on marijuana, hallucinogenic mushrooms and cocaine.
In yet another scoop last October, The ENQUIRER revealed that the former Hannah Montana star's habit of constantly puffing away had pals fearing her life would go up in smoke!
The Voice coach was even stoned during her hosting gig on Saturday Night Live on Oct. 3, ENQUIRER reported — after she licked banana slugs on a druggie camping trip to get high!
Cyrus was "stoned for the entire show," said a source. "She was smoking blunts all week long."
But now, she has turned over a new leaf with Hemsworth after swearing off drugs.
The couple — who met while filming the 2010 movie The Last Song — split in 2013, but reunited earlier this year on a family vacation to Australia. They are planning a splashier second wedding in the U.S. for friends and family, an insider said.
"Liam would never have taken Miley back had it not been for a few new rules, including toning down her X-rated antics on stage and acting more like the future mother of his children," dished a source.
"Miley knows it was hard for him to deal with her wild partying hijinks. She's so grateful Liam is giving her another chance. She's doing everything she can to keep him happy, and quitting weed is a huge deal."
A pal added, "Liam is so proud of her."
