It's the SNL After Party! Featuring Scarlett Johansson, Beyoncé, and Musical Guest Jay-Z!

The 43rd season of "Saturday Night Live" premiered last night, and after the lights went out the cast turnt up!

The party went down at TAO in NYC and all the heavy hitters were there.

In a rare public sighting, show host Ryan Gosling was joined by wife Eva Mendes.

Jay-Z, who performed one of his songs wearing a Colin Kaepernick jersey, arrived with Beyoncé. Leslie Jones made sure to get selfies with them both.

Alicia Keys and Swizz Beatz also made an appearance, as did Diddy.

SNL cast member Colin Jost and love interest Scarlett Johansson even made their first public appearance as a couple -- however they managed to avoid the cameras by coming and going in separate cars.

Alec Baldwin, who kicked off the new season tearing into President Trump, was not there. He's probably already working on material for next week ... we're guessing he'll have plenty to work with.
