Miley Cyrus, the former Hannah Montana actress, is now hanging with Bronx rapper French Montana, and the former Disney star seemed to change her bubble-gum image to hip-hop over Grammy weekend. Cyrus arrived at Ne-Yo’s Midnight Grammy Brunch at LA’s Bagatelle with Montana after tweeting a pic with rapper Wiz Khalifa. “Miley and Montana arrived together and walked in arm-in-arm,” said a spy, adding that the spiky-haired singer then hung with Diddy and Meek Mill till the wee hours. For her album out this spring, Cyrus has collaborated with Khalifa, Mary J. Blige, Pharrell Williams and Tyler, the Creator. And she recently told Cosmopolitan that she’s a fan of Grammy-winning R&B crooner Frank Ocean, who revealed he once had a relationship with a man. “I think it’s going to make him even bigger,” Cyrus said of Ocean’s admission, adding, “Now he’s going to have much more loyal fans . . . If you want to know who’s gonna buy your records for the rest of your life, get Brazilians and gays on your side.” Now that’s an interesting sales strategy.
