And the award for best dance duo goes to… Claire Danes and Gaby Hoffmann!
Following the 22nd Annual SAG Awards in Los Angeles on Saturday, A-listers kept the celebrations going all night at the Weinstein Company and Netflix's SAG afterparty at the Sunset Tower Hotel, which was apparently a place to get down on the dance floor.
The close pals traded in their red carpet gowns for much more comfortable outfits, which consisted of matching Sriracha T-shirts that read "some like it hot," black skinny jeans and canvas tennis shoes.
A ton of other celebrities showed up ready to party, including Orange Is the New Black stars Laverne Cox, Laura Prepon, Uzo Aduba, Diane Guererro and Jackie Cruz.
Demi Moore, Idris Elba, Helen Mirren, Sarah Paulson, Rami Malek, Queen Latifah and Sarah Hyland were also in attendance.
The highlight of the night, however, was when 69-year-old Susan Sarandon joined in on Danes and Hoffman's dance party, showing off her best twerking skills.
Sarandon, who was nominated for her role in The Secret Life of Marilyn Monroe, clearly had a lot of fun on Saturday, as she photobombed the cast of Straight Outta Compton on the red carpet.
She later took to Twitter to reflect on the prank, writing, "Thrilled I got to photo bomb this fine group of actors from one of best films this year!"
Sarandon also got a lot of attention for the cleavage-baring jumpsuit she sported -- even Kate Winslet was impressed! The Steve Jobs actress couldn't help herself from staring, even jokingly placing her hand on Sarandon's chest as the two posed for a pic.
