The Big Bang Theory actress commanded attention as she opted for a floor-length pink gown which showed off her mesmerising curves.
Her gorgeous dress was adorned with sequins and it perfectly showcased Kaley’s slender frame.
Sauntering down the red carpet, the blonde bombshell gave onlookers an eyeful as the figure-hugging frock boasted a deep plunge.
The perilously low-cut design allowed the stunner to flaunt some serious cleavage as she posed for paparazzi.
Ditching her bra for the evening, Kaley was at risk of suffering a major mishap as her assets were only just contained.
The US star’s blonde tresses were styled in loose waves and she wore minimal jewellery to the bash.
Despite Kaley’s big smiles for the camera, she left empty handed as The Big Bang Theory lost out to The Marvellous Mrs. Maisel in the Best Comedy Series category.
During the show, the 32-year-old appeared extremely close to a nip-slip as she took to the stage to present the award for Best Actor in a Drama Series to Sterling Brown.
As she handed over the gong, Kaley’s bust almost completely spilled out in front of the star-studded audience.
The Charmed actress arrived at the ceremony with her fiancée Karl Cook who looked very handsome in a dark brown suit and white shirt.
The couple got engaged at the end of last year after dating for almost two years.
Nicole Kidman also looked sensational at the awards ceremony, held in California, as she stood out in a bright pink long-sleeved dress.
The Australian star stunned in the eye-catching garment which featured sheer fabric across her arms and perky chest.
Nicole walked away with Best Actress in a Movie Made for TV or Limited Series for her role in Big Little Lies.
The hit show – which will return for a second season – also won the award for Best Limited Series.
The drama is based on the novel by Liane Moriarty and stars other big stars including Reese Witherspoon and Laura Dern.
