Miley Cyrus has some big things up her sleeve in 2013. In addition to dropping her new single, "We Can't Stop" on June 3, she might also have some music with Justin Bieber on the way.

She didn't have much to reveal when asked about the rumored collaboration with Bieber, whom she presented with the Top Male Artist prize at the Billboard Music Awards on Sunday, but she also didn't deny something is happening between them. She was photographed leaving his studio last Thursday.

"I know pictures are flying around," she told E! News. "You guys will have to wait and see. I'm the biggest at top secrets. I've had this single ['We Can't Stop'] ready for about a year, and I've had to keep my lips sealed and just not saying anything. So you'll see."

No word on which project the tune will appear on (Bieber is working on new music), but sources add that "something has been in the works for a collaboration." Last month, his manager, Scooter Braun, confirmed to MTV News that Bieber has been writing songs for the entirety of his Believe tour.

For now, fans have to look forward to Miley's Mike Will Made It-produced "We Can't Stop," serving as the first listen of her 2013 album release. "I feel like I can really be myself. I really have more of a connection of who I am, and I feel like I can maybe express that more in my music now," she told Billboard about the single, which will get its first play on Ryan Seacrest's radio show in just a few weeks.

"Me and Mike Will teamed up, and it really just turned out to be perfect and exactly what I wanted, and exactly what I wanted my first sound to be, and my first look to be," she added. "I think it's an important message for me to tell my fans — they haven't stopped waiting, so it's great."
