Newly minted supermodel Gigi Hadid and her sister, fellow model, Bella Hadid, spent Christmas together with their mother, Yolanda Foster and brother, Anwar Hadid, on a ski trip, according to an adorable Instagram the “Real Housewives of Beverly Hills” star posted early on Christmas Day.

And while hanging out together over the holiday, the sisters goofed around on Snapchat, including doing a little song and dance number from the 2006 Disney Channel Original Movie “High School Musical,” while the climactic song “We’re All In This Together” plays. Looks like the Hadids even recreated the original choreography from the film.

One star of the original film, Ashley Tisdale (who played mean girl Sharpay) writes excitedly on Twitter about seeing the stars reenact one of her most famous roles with a bunch of heart-eyed emojis.

And while the TV movie will be celebrating its tenth anniversary on Jan. 20, 2016, that means that the 20 year-old Gigi and 19 year-old Bella were still in elementary school when the film was released. So to them, this is as classic as doing the hand jive from “Grease.”

Which must be enough to make anyone who’s old enough to remember doing the hand jive from “Grease” on the school playground feel practically geriatric.
