Keri Russell Celebrates Win at Netflix Afterparty!

, and Sarah Pidgeon were among the A-listers dancing the night away at the  Actor Awards afterparty in on Sunday.

Hollywood's elite headed to Milk Studios to continue the celebrations following the awards ceremony, which was held at Shrine Auditorium and Expo Hall.

After being awarded the gong for Outstanding Performance by a Female Actor in a Drama Series for her role in The Diplomat, Keri was in the mood to party.

Keri, 49, waved her blue statuette in the air in one hand and her clutch bag in the other, joyfully boogying around the room following her big win.

The actress looked stunning in an elegant black one shoulder gown, which she wore with a pair of dramatic drop earrings and a slick of red lipstick.

Kate, who was nominated in the Outstanding Performance by a Female Actor in a Leading Role category for Song Sung Blue, was also at the bash.

After losing out on the award to Jessie Buckley, Kate, 46, was spotted quaffing champagne while linking arms with fellow actress Ali Larter.

Kate slipped out of her white awards dress and into a slinky silver number, which showcased her incredible physique.

She also threw her arms around  Rose Byrne and wrapped her into a hug.

Star of the moment, Sarah Pidgeon, who portrays Carolyn Bessette in Love Story: John F. Kennedy Jr. & Carolyn Bessette, joined them at the celebration.

Sarah, 29, who was wearing a strapless lilac dress, was pictured chatting on the phone after kicking off her heels on the dancefloor.

Demi Moore mingled at the party wearing her black dress which featured a dramatic tulle train, which followed her around the party.

Also there was Aimee Lou Wood, who was nominated for Outstanding Performance by a Female Actor in a Drama Series for her role as Chelsea in The White Lotus.

Despite missing out on the win, Aimee Lou still enjoyed the night with her peers at the after party.

Ahead of the bash, Michael B. Jordan pulled off the upset of awards season as he beat Timothee Chalamet for the top acting prize at the Actor Awards, formally known as the SAG Awards.

That was not the only massive surprise for the talented star as his film, Sinners, also shocked as it earned top prize Outstanding Performance by a Cast in a Motion Picture at the event which took place at The Shrine Auditorium and Expo Hall in Los Angeles.

The 39-year-old star was left in tears as he earned the win in the Outstanding Performance by a Male Actor in a Leading Role.

He beat Chalamet who starred in Marty Supreme in a field which also included: Leonardo DiCaprio - One Battle After Another, Ethan Hawke - Blue Moon, and Jesse Plemons - Bugonia.

Jordan was bewildered as he looked down at his new actor trophy with his hands at his face and his mouth fully open.

Chalamet, 30, - who previously won at the Critics Choice Awards and Golden Globe Awards - was a good sport as he stood up and applauded Jordan alongside his co-star Gwyneth Paltrow, 53.

When his name was announced, it was his mother Donna Jordan who had a shocked look on her face as she joyfully grabbed his shoulders.

During his speech, Jordan recognized his mother in a very sweet way as he said: 'Mom, thank you for driving me back and forth to New York, when we didn’t have enough money to go through the Holland Tunnel.'

The veteran actor went on to thank his peers who voted for him to earn his crowning moment while admitting that he wasn't expecting this win.

Jordan said: 'I wasn’t expecting that. I’m so honored and privileged to be nominated in categories with people and actors and humans that I love, and I love their work and what they contribute to our craft and just rise to has been unbelievable.

'So, thank you for welcoming me in and making me feel seen.'

It was not just Jordan's mother's reaction that had people talking as presenter Viola Davis' jaw dropped when she opened up the envelope before she announced the star as the winner and shouted in celebration.

The Ryan Coogler written and directed horror flick later earned the top ensemble acting prize over Frankenstein (Netflix), Hamnet (Focus Features), Marty Supreme (A24), and One Battle After Another (Warner Bros).

Delroy Lindo spoke out on behalf of the cast as they earned Outstanding Performance by a Cast in a Motion Picture just one week after he and Jordan were presenting at the BAFTAs last weekend when a guest with Tourette's bellowed the word 'n*****' at them.
