After the media hoopla that ensued following Billy Ray Cyrus' divulgence of his daughter's wedding plans, Miley Cyrus is now discrediting her father's words and tells "Entertainment Tonight" that her father "knows nothing" about her upcoming wedding plans with Liam Hemsworth.

Last week, Billy Ray revealed that his 19-year-old daughter would have three separate wedding ceremonies to celebrate her marriage, but Miley says her father fabricated her plans to the media.

"I don't know what my dad is doing or where my dad is on the planet," she told "ET." "My dad knows nothing. I don't know what he is making up ... I hate to put him on blast, but he doesn't know what he's talking about."

Cyrus and her "Hunger Games" fiance became engaged this summer after they rekindled their relationship, which initially sparked while the two were working on the "Last Kiss" film together.

While the "Hannah Montana" star called her dad out on his revelation to the media, she confessed that she sometimes stirs the pot and creates rumors for her own amusement, just as her father did.

"He does what I do when he's sitting in a press thing: He's like, 'Let's make this fun. Let's make stuff up. Let's get the ball rolling on some good rumors because I'm bored and I can start something,'" she said.

Tune in to "ET" tonight for the full story.
