“I'm ENGAGED!" she laughed, clearing up two rumors in one, TMZ reports. "I'm engaged. That is impossible."

There were rumors Bieber and Cyrus left Beacher’s Madhouse at the Roosevelt Hotel together around 2am after partying into Sunday morning. However, it seems she’s still working on her relationship with Hemsworth.

Cyrus also discusses Bynes’ recent Twitter attack on her, but she says she won’t even “entertain” it. She adds that Bynes might be seeking attention, since Cyrus’ name was trending worldwide on Twitter.
