At the Critics' Choice Awards, pregnant Kaley Cuoco exclaims that her maternity attire "feels perfect."

At the Critics' Choice Awards, Kaley Cuoco experienced a unique pregnancy fashion moment.

The pregnant Flight Attendant actress, who is wearing a stunning black Dior Couture gown, attended the 28th annual Critics Choice Awards on Sunday. She expressed her appreciation for the long-sleeved black dress while posting pictures from the event on Instagram.

She tagged the upscale clothing company and said, "Thank you for this incredibly elegant, amazing outfit!" She thanked her glam staff for helping her feel "perfectly pregnant," adding, "Thank you guys."

Tom Pelphrey, her boyfriend, was by her side throughout the evening and shared a set of photos from the event praising his partner.

"Look at yourself. So. Stunning. ALWAYS, "He captioned the photos and tagged her team.

Cuoco and Pelphrey celebrated the arrival of their baby girl earlier this month with an extravagant, fun-filled baby shower. Briana Cuoco, Cuoco's sister, planned the event, which included a live band, a multi-course dinner, and dancing.

Tennis player Prakash Amritraj, former Bachelorette Ali Manno, and actress Ashley Aubra were among those in attendance, as were the actress's mother and father. Brad Pitt was also present to congratulate the happy couple.

Cuoco posted a series of photos from the party to Instagram, along with a caption about how much love she and Pelphrey were feeling.

"Last night we got to celebrate our future unicorn in the most magical environment with incredible friends, family, and animals," she wrote. "Thank you to a very special group of people who helped make it a night we'll all remember for the rest of our lives."

Cuoco is looking forward to seeing the two grow into their new roles as mom and dad, with sources telling PEOPLE that Pelphrey will be a "hands-on dad."

"Kaley is at ease with Tom as a mate and father, at ease with the significant change the baby will bring to their lives, and at ease with her work," the source said. "They are preparing for the impending arrival. She's in a good spot."

Pelphrey revealed to Extra in October that the couple is expecting their first child ""I'm overjoyed" to be having a baby girl: "It's the most incredible thing. Very fortunate... Very lucky... Very fortunate... Everyone is in good health. It's a lovely thing."
