Amanda Seyfried immediately topped best dressed lists when she hit the red carpet at the 17th annual SAG Awards on Sunday, Jan. 27. Seyfried, 27, wowed the crowd when she arrived in a stunning strapless navy mermaid-style gown by Zac Posen at the Los Angeles Shrine Auditorium. To the actress' disappointment, however, her second look of the night failed to come through for her.

Seyfried attended an after party following the awards ceremony at the Charteau Marmont. When she left the event and stepped into a chauffeured-driven car, her lace dress with sheer panels exposed her bottom to paparazzi. Unbeknownst to the "Red Riding Hood" star, photographers took multiple shots of her g-string underwear as she climbed into the back seat of her waiting car.

Seyfried joined a growing list of celebrities with wardrobe malfunctions that have occurred in and out of their cars.

Last month Seyfried's "Les Miserables" co-star Anne Hathaway unknowingly flashed photographers at the New York premiere of their film on Monday, Dec. 10.

The 30-year-old stepped out of her chauffeured SUV at the Ziegfeld Theater in New York City and accidentally revealed she wasn't wearing any underwear to the event. The wardrobe malfunction added Hathaway to the Hollywood club of other infamous starlets who have also notoriously flashed photographers when they stepped out of vehicles, namely Britney Spears and Lindsay Lohan.

Seyfried wasn't the only actress to experience a wardrobe malfunction the night of the SAG Awards. Earlier that night during the ceremony, Jennifer Lawrence's tiered Christian Dior Couture gown ripped in half when she stood up after her name was announced that she had won the Outstanding Female Actor in a Lead Role for "Silver Linings Playbook. 

Lawrence's dress split in two as she hugged and kissed her "Silver Linings Playbook" cast members and crew before making her way to the stage. However, when Lawrence arrived on stage to accept the win from the presenter, Robert DeNiro, her dress appeared intact. Thankfully, the incident happened so quickly that television viewers did not see the malfunction.
