Kaley Cuoco celebrated her Golden Globes loss by eating pizza and drinking champagne on the floor

• Kaley Cuoco received her first Golden Globes nomination for her role in "Flight Attendant."
• After she lost to Catherine O'Hara on Sunday, Cuoco ate pizza and drank champagne in her ball gown.
• “I would like to thank...never mind !!” she captioned a photo of her post-award show festivities.

Kaley Cuoco didn't let her Golden Globes loss stop her from enjoying an after-party with pizza, champagne, and sweets.

The 35-year-old received her first Golden Globes nomination for best actress in a TV series musical or comedy for her performance on HBO Max's "Flight Attendant." On Sunday, the award went to "Schitt's Creek" star Catherine O'Hara.

Cuoco didn't seem to take the loss too seriously, though.

She shared an Instagram photo of her post-show festivities, during which she sat on the floor in her ball gown surrounded by pizza, champagne, and sweets.

The actress captioned the photo: "I would like to thank...never mind !!"

Cuoco also congratulated her fellow nominee O'Hara on securing her first Golden Globes win, adding that her victory is overdue.

"Congratulations, Catherine O'Hara! You are a queen, an icon, and I will happily lose to you any single day. It has been an honor," she said on her Instagram story, blowing a kiss at the camera.

She continued, "I'm so happy for you. You should've gotten one of these ages ago."

Over the weekend, Cuoco shared a photo of herself meeting O'Hara, her "comedy queen," for the first time ahead of the Golden Globes.

"She's everything I hoped and dreamed," Cuoco captioned the photo.

Cuoco, who was also a producer on "Flight Attendant," had a string of emotional moments ahead of the 2021 Golden Globes.

She burst into tears when nominees were announced in early February, sharing a video on Instagram of herself hearing the news for the first time.

Cuoco cried again the day before the show when her husband Karl Cook surprised her by returning early from a work trip.

"Most of you know [Karl Cook] has been away for many weeks and has many weeks of travel so I knew he wouldn't be back to celebrate the globes with me," she wrote on her Instagram story, continuing, "The event is virtual so I wasn't gonna force him to fly home for it, I knew he had a crazy schedule."

Cook, who married the actress in 2018, shared several behind-the-scenes moments from their day-of celebrations on social media.

Cuoco was also emotional when she got dressed ahead of the Golden Globes. Styled by Brad Goreski, Cuoco wore an Oscar de la Renta gown, Stuart Weitzman shoes, and Harry Winston jewelry.

In Goreski's Instagram story Sunday, he shared a video of the "Flight Attendant" lead saying that she teared up when she put the dress on.

"I feel like Cinderella," she said in the video. "I love it so much."
