In the first of the photos Lopez shared Saturday in celebration of her 52nd birthday, the edge of a black-and-white snapshot featuring the "Cambia El Paso" singer and Affleck, 48, astride a motorcycle could be seen. The photo was taken in the early 2000s when they were first together. Although Lopez's pal Leah Remini previously posted a photo of her and Affleck at her birthday party, Saturday marked the first time the lovebirds shared a glimpse at their relationship on their own social media accounts.
