Jennifer Lopez shared a heartfelt Instagram post on Sunday dedicated to her 16-year-old fraternal twins, Emme and Max. The 55-year-old entertainer, who recently celebrated her birthday in the Hamptons, posed with her children in two photos. In the caption for her 251 million followers, she wrote “My whole heart,” accompanied by green and white heart emojis.

This affectionate post followed her birthday celebrations in the Hamptons, during which her husband Ben Affleck remained in Los Angeles. In one photo, Jennifer, wearing stylish square sunglasses, smiled with Emme, whom she refers to using they/them pronouns.

Another photo, apparently taken at a different time, featured Jennifer in a green and white patterned dress with Max, who wore personalized white pajamas and had an arm around his mother’s shoulder. A third image showed Emme and Max cuddling together as toddlers.

Jennifer shares her twins with ex-husband Marc Anthony. Her Instagram post garnered over 360,000 likes within an hour.

The Bronx-born star turned 55 on July 24 with a series of lavish celebrations, noticeably absent from which was her husband of two years, Ben Affleck, 51. The couple, rumored to be facing marital difficulties, have not been photographed together since early June. Reports indicate that Ben recently purchased a $20.5 million mansion in Pacific Palisades, further fueling speculation.

Jennifer is also stepmother to Ben’s three children with ex-wife Jennifer Garner: Violet, 18, Fin, 15, and Samuel, 12. According to insiders, the children have been trying to help repair their parents’ marriage, believing them to be deeply in love and not wanting them to divorce.

Sources close to the situation suggest that the couple’s issues are more profound than public speculation about Jennifer’s fаme. They even reportedly spent their second wedding anniversary on July 16 apart.
