Miley Cyrus: 'My New Music Is Gonna Shut Everyone Up'

One day later, Cyrus lobbed a few shots on Twitter after teasing fans last week that she was listening to her new full-length "start to finish."

"My new music is gonna shut everyone up," Cyrus -- who has worked with Pharrell Williams, Hit-Boy and Mike WiLL Made-It on the album -- posted on Twitter. "Not discussing anything but my music from now on." She also shot down rumors of trouble in paradise with fiancee Liam Hemsworth: "I am so sick of La. And sick of the lies that come with it. I didn't call off my wedding. Taking a break from social media. #draining"

One thing that Cyrus is not taking a break from: randomly hanging out with rappers. The singer makes a cameo in the music video for Tiffany Foxx's new single "Twisted," which was released on Thursday. In the clip, Lil Kim and her hip-hop protege rap about being "Twisted, twisted, twisted/I can barely feel my faaaaace," while Cyrus, sporting some feathered shades and golden hoop earrings, gleefully dances behind them.

The "Party in the U.S.A." star is coming off the lackluster sales of "Can't Be Tamed," which has moved 344,000 copies according to Nielsen SoundScan and was the pop star's last album with Hollywood Records. In a January interview, Cyrus revealed that she worked with Odd Future leader Tyler, The Creator on her still-untitled new album.
