The Facebook-owned photo-sharing app has become the go-to place for fans to catch a glimpse of the Memorial Day weekend festivities. Wedding guests took to Instagram and Twitter to share moments from the reception, Givenchy creative director Riccardo Tisci posted a photo of the dress he designed for Kardashian, and the couple chose the online platforms to share their first official wedding photos.

Kardashian isn't the only celebrity to use Instagram to share big news. Actor Channing Tatum posted the first photo of his daughter with wife Jenna Dewan on Instagram last Father's Day, and supermodel Gisele Bundchen revealed a rare Instagram photo of her wedding to football player Tom Brady on their fifth anniversary.
