It isn't a secret that Miley Cyrus has a fascination for marijuana. Apart from being photographed several times holding weed, some of her performances also included the drug. One of her controversial birthday cakes also showed a naked Miley whose private parts were covered with weed.

Her penchant for marijuana is reportedly causing her parents to worry that they suggested a rehabilitation program. According to One News, it is Billy Ray who is urging the former Disney star to enter rehab. Even Dolly Parton, Miley's godmother, has joined the pleading camp.

However, the 22-year-old refused. Aside from cannabis, the "Adore You" songstress once admitted in a Rolling Stone interview that she also experimented with ecstasy. She even called them "happy, social drugs" as they helped her forge social relations.

"Miley said a lot of people have been trying to get her into rehab, but it's not something that she's interested in," claimed one source to The Sun.

Recently, the "Wrecking Ball" hit maker unknowingly posted a photo on Instagram showing what appeared as a rolled-up bank note and a vial of white powder. She was reportedly working on a new song in the wee hours of the morning when the photo was taken.

Her representatives are yet to comment about allegations on Cyrus' drug use. Meanwhile, will the latest Miley Cyrus scandal affect the singer's romance with Patrick Schwarzenegger?

The young model's family is reportedly worried about the couple especially Cyrus' influence on Schwarzenegger. While his mother Maria Shriver is warming up to the "So Undercover" star, the same thing cannot be said of Schwarzenegger's sister.

Last December, Liam Hemsworth's ex allegedly did not get invited to Katherine Schwarzenegger's birthday bash.
