The only difference is, they tend to be somewhat more glamorous. Taylor Swift, for one, is clearly partial to a party and a fancy dress one at that.
The singer threw a costume bash that saw her dressing up as Ariel from "The Little Mermaid."
Guests were asked to attend dressed as their childhood heroes, and they didn't disappoint.
Alongside Swift's Ariel, Gigi Hadid came as everyone's favourite nanny, Mary Poppins.
Blake Lively donned her finest gingham dress as Dorothy from "The Wizard of Oz" (complete with Toto in a basket), and husband Ryan Reynolds was also at the bash although seemingly not in character he was dressed in a grey suit, white shirt, and red tie (undone at the time of photo-taking).
Reynolds was also papped enjoying a bottle of Aviation Gin, a company in which he invests.

Other guests pushed the boat out somewhat more than Reynolds, though, dressing up as Cinderella, Nancy Drew, Posh Spice, Rizzo, Frida Kahlo, and Steve Irwin amongst others.
Judging by the photos, Swift ensured her guests were thoroughly nourished by providing plenty of pizza, crudits and dips, cookies, and acheeseboard.
Upon seeing the pictures, most people were left wondering just one thing: How do we get an invitation next year?
One fan said her goal for 2019 was to be invited to Swift's NYE party.
"Imagine being invited to Taylor Swift's New Year's Eve party," wrote another fan on Twitter.
Others said that if they hadbeen invited, they'd have dressed as Swift herself.
They just want to be part of her world.
