Rumer Willis miami florida dress red carpet Rumer Willis miami florida dress red carpet

Rumer Willis hit the red carpet at the Miami International Film Festival looking gorgeous in a skintight Herve Leger dress while promoting her latest flick The Diary of Preston Plummer.

Now that her mom, Demi Moore, is back from treatment, Rumer is ready to be in the spotlight once again ... moving forward with her career.

During the past few months, Rumer has been constantly by her mother's side in the hopes of getting Moore back on track. The 23-year-old actress was also present during the 911 call that was made after Moore reportedly collapsed from doing whip-its ... gaseous canisters of nitrous oxide often inhaled from whipped cream dispensers. With treatment behind her, let's hope Demi is back on the right track.

We have to admit ... Rumer is looking fierce!
