Sarah Paulson fans can’t get over 81-year-old girlfriend Holland Taylor’s iconic behaviour at 50th birthday party

Sarah Paulson fans can’t get over her 81-year-old girlfriend Holland Taylor’s iconic behaviour at her 50th birthday party.

The American Horror Story star - whose birthday is on 17 December - celebrated the milestone birthday over the weekend along with a number of other very familiar faces.

Joining Sarah and Holland for the bash were Wicked's Cynthia Erivo, Pitch Perfect's Elizabeth Banks, Modern Family's Jesse Tyler, Gladiator II's Pedro Pascal, Poetic Justice's Regina King and director Anthony Hemingway.

Anthony, along with many of the other fellow celebrity guests, shared a series of pictures and videos from the night to social media.

He captioned one Instagram photo dump: "It’s the 17th all month! HAPPY 50th my dear friend @mssarahcatharinepaulson of 29 incredible years! Last night was a whole vibe - nothing but love, laughs, and the kind of joy you bring to everyone in the room.

"You’re a Golden Milestone, walking sparkle, and a nonstop source of brilliance (and those ridiculous belly laughs). Love you forever and then some. Here’s to many, many more of your magic!"

Naturally, it didn't take long for fans to rush to the comments to gush over Sarah's birthday celebrations - as well as Holland's dance moves seen in one the video posts.

One penned: "I loveeeeeee everything about everything in this post!!!"

"HOLLAND HAS MOVES," wrote a second, while a third echoed: "Holland is a national treasure."

A fourth chimed in: "I wanna party with the cool kids next time."

Someone else commented: "The turn up is absolutely magical!"

While another chirped: "This party group is [fire emoji]."

And a final Instagram user added: "VIBEEEESSSSS!"

Holland and Sarah have shared almost a decade together despite scrutiny regarding their 32-year age gap.

The duo first met in 2005 but didn't go public with their romance until 2015.

Appearing on the Smartless podcast, hosted by fellow actors Will Arnett, Jason Bateman and Sean Hayes, Sarah opened up about her relationship.

She said: "We don’t live together, that’s the sort of secret.

"Holland and I, we spend plenty of time together but we don’t live in the same house.

"We’ve been together for a long time now and I think part of it has to do with, we’re together when we wanna be and we’re not when we don’t."

It sounds foolproof, even though so many of us are conditioned to a 'traditional' living situation with our partners.

Sarah was then asked whether it was possible they could just sleep in separate beds, rather than in separate houses altogether - and her reply had us swooning.

She said: "No, because we like to fall asleep holding hands, Holland and I. We sleep holding hands. I like to sleep near her."

The actor then joked: "I don’t want to be around her the rest of the time."

“Just kidding", Sarah added, laughing.
