You’re in luck! Elton John and David Furnish took to Instagram to encourage fans to celebrate their nuptials with them, which will take place on Sunday. The singer – who is brand new to Instagram – posted an invite to the wedding as his very first photo. “Sir Elton John and David Furnish request the pleasure of your company to celebrate their wedding on Sunday the 21st of December,” reads the invite. Fans can expect details from the wedding – which will reportedly take place at their Windsor estate – to unfold throughout the day on their individual accounts. “Please join us this Sunday @DavidFurnish and I will be posting special moments from our big day. #ShareTheLove #EltonJohn #DavidFurnish,” John, 67, captioned the photo. The couple – who are parents to sons Zachary and Elijah – entered a civil partnership in 2005. Their decision to officially tie the knot comes after England’s legalization of same-sex marriage in March. PHOTOS: The Sweetest Snaps from Elton & David’s Wedding
