Although wedding rumors between Miley Cyrus and Liam Hemsworth have been floating around since the "Wrecking Ball" singer slipped that Neil Lane engagement ring back on her finger, it now sounds like the couple's nuptials truly are on the horizon—but you won't be able to get many big-day details out of this bride-to-be. Reportedly, the wedding Miley Cyrus is planning with Liam Hemsworth is super secret.

According to a source who spoke to Entertainment Tonight, after their years-long relationship, Cyrus and Hemsworth may finally be ready to tie the knot. "They have been in love for almost nine years, but the timing has never been right until now," the source says. "Their massive careers, their ages, and their families' input has kept them from getting married."

The source added that the stars' families were a major influence in their decision to wait, saying, "While Miley's parents have always adored Liam, Liam's parents were not sold on Miley and her outrageous behavior. Miley has been very open about her drug and alcohol use, and that didn’t bode well with his family's far more conservative lifestyle."

The "Malibu" singer has admitted that she is distancing herself from her previous party-girl lifestyle and has quit using drugs, which has resulted in a stronger relationship with her beau's family. "Miley had to get through a phase of discovering herself before she was able to commit. And now that she has turned her life around and stopped partying, she is clear minded and knows what she wants," the source added. "Liam's mother [Leonie] is finally over the moon to have her as a daughter-in-law."

Additionally, Liam's sister-in-law, Elsa Pataky, helped Cyrus win over Mama Hemsworth. "Elsa and Miley have always been very close, and Elsa really went to bat for Miley," the source says. "She has tried to impress on her in-laws all the big changes Miley has made to turn her life around and build a future with Liam."

Rumors that the two had secretly wed were spread this time last year when Cyrus was first spotted with a gorgeous wedding-style ring, but the source revealed that this was simply a sign of their commitment to each other. "She had been sporting her ring and wanted him to show his love and commitment in the same way," the source says. "Their friends refer to their rings as 'promise rings,' and Liam and Miley are both good with that."

As for wedding plans, the two are being quite secretive about their nuptials. Cyrus allegedly wants to have an intimate, ranch-style wedding to pay homage to her country roots, but she isn't giving away any details just yet.

"Miley has come up with all sorts of different wedding plans. She is always creative and thinking of new ideas that will make her experience different," the source said. "She hasn't announced anything because she is being very secretive, so only their friends will know, and at the very last minute. This time they are doing everything their own way."
