She left viewers in hysterics with her appearance in an amusing Finger Lakes sketch.

And Kim Kardashian put on another showstopping display in her stunning silver gown as she headed to Saturday Night Live’s star-studded 50th Anniversary after party at New York’s Plaza H๏τel on Sunday.

Showing off her famous curves, Kim wowed in her dramatic metallic gown as she headed into the party.

The star was joined by hitmaker Lady Gaga, who slipped into a stylish grey dress as she entered the party with fiancé Michael Polanski.

During the special, Kim made a surprise appearance as a member of the Maharelle Sisters from the Finger Lakes, regular guests on the sketch-comedy show’s version of The Lawrence Welk Show.

Kim elicited gasps and cheers from the audience as returning star Kristen Wiig drummed on her pert derriere.

She had the character’s long doll hands, extended forehead and snaggletooth.

‘Forehead!’ he exclaimed.

Kim, who has lately been expanding into acting after becoming one of the biggest reality stars of all time, got a chance to sing in character with Ana and Scarlett in a babyish voice. 

But they were interrupted when Kristen began to rub her tiny hands over their faces.

Kim was a good sport as she turned around to show off her famous derriere while Kristen started spanking it with her doll arms.

The backing band’s drummer got in on the action and doubled Kristen’s rhythm on the drum set.

Kim was joined by hitmaker Lady Gaga, who showed off her quirky sense of style in a grey satin gown as she arrived for the party with her fiancé

Despite initially being turned off by Kristen’s character, Will found himself oddly turned on by her after a third doll hand appeared out of nowhere as she tried to pry open his mouth. 

‘I can’t believe I’m saying this, but I think I love you,’ he said, surprising himself.

Later in the evening, Tina Fey and Amy Poehler kicked off a star-studded segment of audience questions, modeled after a cliched opening-monologue tactic.

The comedy stars and former Weekend Update cohosts both looked glamorous in all-black as they let the biggest stars in the audience pipe up with questions.

The most surprising of the questions came from Ryan Reynolds, who was accompanied by his wife Blake Lively.

The two have been laying low in recent weeks amid Blake’s Sєxual harᴀssment lawsuit against her It Ends With Us director and costar Justin Baldoni, as well as his subsequent $400 million defamation lawsuit against her, Ryan and her publicist.

Shockingly, Ryan — who did all the talking — even alluded to the controversies when he piped up.

The ᴅᴇᴀᴅpool star put on a comically cagey expression after Tina asked him how things were going.

‘Great,’ he replied in a perfect ᴅᴇᴀᴅpan while folding his hands nervously. ‘Why, what have you heard?’ 

Blake then looked up at him with a painfully over-the-top expression of concern, before relaxing into her normal smile.

For his bizarre question, Ryan asked if the material used to create the show’s prosthetic coneheads was edible. 

‘Edible? No. And based on them being made in 1975, I’d ᴀssume they’re highly toxic,’ the women replied. 

‘Oh, OK,’ he said, playing it cool. 

‘So if somebody hypothetically took a couple nibbles backstage and got excited, should they go to the hospital or should they…?’ Ryan continued, before trailing off.
