Gigi Hadid and boyfriend Zayn Malik celebrated the Muslim holiday of Eid al-Adha this week and showed off their Muslim pride with an Instagram photo shot with their moms. So cute that the families are getting together!

The 22-year-old supermodel posed with her mom, former model Yolanda Foster, and Zayn with his mom Trisha and the snap was posted by both moms and captioned "Eid Mubarak," which means "blessed celebration."

So for those who don't know, Eid al-Adha is the holiest of Muslim holidays and the name means "Feast of the Sacrifice."

It seems neither Gigi nor Zayn are actually practicing Muslims -- Gigi's father is Palestinian and Zayn's father is Pakistani. Yolanda is Dutch and Zayn's mom Trisha is British, but apparently all four of them have great respect for the Muslim religion and recognize its influence on their upbringings.

Zayn told the Evening Standard back in June: "I take a great sense of pride — and responsibility — in knowing that I am the first of my kind, from my background. I’m not currently practicing but I was raised in the Islamic faith, so it will always be with me, and I identify a lot with the culture. But I’m just me. I don’t want to be defined by my religion or my cultural background."
