Celebrity sisters Gigi Hadid and Bella Hadid cut loose for fans over Christmas by engaging in a little song and dance to High School Musical!

Gigi, 20, and Bella, 19, were seen dancing in a Snapchat video to "We're All in This Together," the ensemble track featuring stars Zac Efron, Vanessa Hudgens, Ashley Tisdale and Corbin Bleu. High School Musical debuted on the Disney Channel in 2006 and became such a big hit for the network that it spawned two more sequels.

The Snapchat video caught the attention of Tisdale, who tweeted her excitement over seeing the Hadid sisters dancing to the song.

According to People, the sisters are currently vacationing with family in Aspen, Colorado.

Both Hadid sisters have been in the news recently regarding their personal lives. After dating Cody Simpson and Joe Jonas, Gigi is reportedly linked to former One Direction member Zayn Malik. Meanwhile, it was reported yesterday that Bella Hadid's relationship with The Weeknd might be on hold for the time being.
