Rumer Willis Shows Skin At 'The Diary Of Preston Plummer' Premiere (PHOTOS)

Rumer Willis stunned on the red carpet at Monday's premiere of her new movie, "The Diary of Preston Plummer," sporting a figure-hugging nude dress with a plunging neckline.

Willis was all smiles at the Miami International Film Festival event, though her thoughts were undoubtedly with mother Demi Moore, who recently returned to Los Angeles after a stint in rehab. After suffering from seizure-like symptoms on January 23, Moore entered a rehabilitation facility in Sundance, Utah to address her eating disorder and addiction issues.

But Willis should be at ease knowing that, following Moore's hard work at rehab, her mother was able to get away from the media's close watch, on vacation at an undisclosed location.

We have a feeling that a rested Moore will be back on the red carpet, cheering on her daughter's budding acting career in no time.

Check out Rumer's racy look below:
