Miley and Liam pose at 'Paranoia' premiere

Miley Cyrus was on the red carpet Thursday in Los Angeles to support sweetie Liam Hemsworth at the premiere of his new movie, Paranoia.

They posed together arm-in-arm. She was all smiles.

And she seemed to be on her best fashion behavior as she was demure in a knee-length leather dress with her hair combed to the side, a departure from the naked or near-naked photos she has been sharing of late.

And she left the press to Liam, reports E!

When one reporter playfully asked for a twerking lesson on the spot, she laughed and said, "Not tonight!"

Meanwhile, you can see Miley wearing miles of fabric as she goes glam in haute couture gowns and other outfits in the September issue of Harper's Bazaar.
