People Editorial Guidelines Published on August 26, 2016 05:00 PM Share Tweet Pin Email Photo: Raymond Hall/GC Images Jennifer Lopez may be going through a difficult time in her personal life, but she wants fans to know that she’s taking care and putting herself first. The 47-year-old superstar was snapped on the set of her crime drama Shades of Blue in New York City standing over a sidewalk painting that reads “Protect Yo Heart.” The slogan is part of a popular series of N.Y.C. street art, but the piece takes on a whole new meaning in light of her recent split with longtime boyfriend Beau "Casper" Smart. She shared the photo on Instagram Friday afternoon, along with a caption playfully calling out Elaine Goldsmith-Thomas, the hit show’s executive producer and her longtime producing partner. Goldsmith-Thomas had shared the photo herself, but accidentally cropped out the text on the street art. Clearly, J.Lo wanted to get her message across: She’s protecting her heart at all times! PEOPLE broke the news on Wednesday that Lopez and Smart have ended their relationship after being romantically involved since 2011. “Jennifer and Casper have split,” the source said. “They have not been together for a few weeks.” The last time the couple was seen in public was at Lopez’ star-studded birthday party on July 24. “It wasn’t anything dramatic and they were on good terms – it just came to a natural end,” the source adds. “They will remain friends and they see each other, but they are not together. It was very amiable.” A rep for Smart declined to comment on the split, while a rep for Lopez had no comment.
