Arriving to the star-studded bash, the mum-to-be turned heads in her daring getup, proving she can still give us style inspo even when she's expecting.
How gorgeous did she look?
Posing for photographers, Chrissy just about put her growing tum on display. The starlet hasn't quite popped yet, but you can still make out the outline of her bump thanks to her fitted getup.
Chrissy flashed her pins for the bash, braving a stylish pencil skirt that featured a risqué thigh-high split and teaming it with a ribbed turtle neck top. She then added mesh court heels on her feet, styled her ombre locks into tousled waves and painted a slick of vampy berry-hued lipstick on her lips.
Showing off her look for the evening, the 29-year-old wore a huge smile on her face while cutely placing a hand on her baby bump.
Chrissy was without her husband John Legend. but rubbed shoulders with Halle Berry, Kaley Cuoco and her Big Bang Theory co-star Johnny Galecki.
Chrissy's appearance at the launch comes nearly a month after she first announced she was pregnant.
After openly speaking about her struggle to conceive in the past, an excited Chrissy revealed she and John are now expecting their first child together.
She took to Instagram on 12 October, sharing a photo of herself and John, with the 'Ordinary People' singer placing a hand on her stomach in the picture. Alongside it, she gushed: "John and I are so happy to announce that we are pregnant :)."
Chrissy then added: "As many of you know, we've been trying to have a baby for a while now. It hasn't been easy, but we kept trying because we can't wait to bring our first child into the world and grow our family."
John and Chrissy's baby joy comes two years after they wed. The pair married on 14 September 2013 in Como, Italy - just over a year after John popped the question.
