"Anytime I'm here, I'm like, 'Honey, move over. Let me show you,'" said Miley Cyrus, only semi-joking. "I'm excited for next year when hopefully my record's done and people are hearing my tunes and digging it."

The actress/singer expects to have something out by the end of this year.

"I've waited two years to put out a record, so I really want that first thing that I say to be something really important," Miley said.

Taylor Swift is officially scheduled to drop her fourth studio album October 22 and she was already dressed for the album's release.

"I just like red a lot more now that my album's called Red," said Taylor, dressed in scarlet, from her lipstick to her fingernails.

The pop star explained the album's title, saying, "The emotions dealt with on this album are the red ones: intense love, infatuation, passion -- all those things."
