Jena Malone, who plays the sarcastic, rebellious District 7 tribute in “Hunger Games: Mockingjay, Part 1,” battled to keep the top of her sexy, off-the-shoulder gown from sliding down at the movie’s London premiere.

The 29-year-old actress posed on the red carpet like Marilyn Monroe, bending her knees, arching her back and throwing back her head.

The thigh-high split up the front of her gown parted more than once to reveal her bare legs and a hint of her panties.

Malone probably kept moving because of the London chill in the air. Jena grew up in Sparks, Nevada, just outside Reno, the state capital, where it’s considerably warmer.

Jena had a semi-nude scene in “Hunger Games: Catching Fire” when her character tried to intimidate Katniss by taking off her clothes.

She protects Katniss in the Quarter Quell and is rescued with Peeta and Annie in Mockingjay. She joins Katniss in District 13 for the rebellion and the two become close.

Jena will also appear in “Inherent Vice” a crime comedy-drama that stars Joaquin Phoenix, Josh Brolin, Owen Wilson, Katherine Waterston, Reese Witherspoon, Benicio del Toro, Maya Rudolph, and Martin Short.

It hits theaters Dec. 12.
