Scarlet fever!

Amber Heard definitely turned up the heat at the premiere of The Rum Diary (which stars Johnny Depp) in Los Angeles on Thursday night.

The actress, 25, arrived in a red strapless gown by Elie Saab, which featured a sexy, almost waist-high slit. She paired the stunning look with nude Christian Louboutin peep-toe heels, a sophisticated updo and gorgeous makeup.
