After unwittingly treating us to a few minutes of rare, steamy PDA between her and R-Patz at the premiere of her own film “On The Road,” Kristen gave us one more thing to drool over during Cannes season—her gorgeous red carpet look for “Cosmopolis”!

The actress, who landed herself on Vogue’s “Best Dressed” list last year, certainly lived up to the title in a bright, hot red Reem Acra sleeveless gown, which featured a daring neckline, a sexy lace back, and small lace panels along the torso.

Kristen paired the dress with red heels and simple gold jewelry.

Matching red lips and a purposely-messy updo finished Kristen’s look.

Oh, and in case you were wondering, the man she’s posing with is Rob’s best friend—and Sienna Miller’s fiancé—Tom Sturridge.

What can you say about Kristen’s latest red carpet effort?
