Lynda posted about the France getaway herself via Instagram Stories on Sunday, dubbing it “the best double birthday sister trip [she] could have dreamed of.” She went on to thank Jennifer before highlighting the bathtub shot, which was a “peak” moment of the trip. When the “Office Romance” actress turned 56 last year, she honored the milestone with an over-the-top party in Turkey. Lynda called her getaway with Jennifer (pictured above) “the best.” @jlo On Jennifer’s last birthday, she released a song in honor of the milestone. jlo/Instagram She was on tour at the time and debuted her “Birthday” song earlier that evening. “Name on top of the cake, it’s my birthday / I’ma make this famous ass shake, it’s my birthday,” the actress sang at the time. “Throwin’ all this money in they face, it’s my birthday / Every day is my birthday, bitch.” Six months later, Jennifer acknowledged “some of the things” social media users say about “dress[ing] her age” — and issued an epic clapback. Months later, she clapped back at haters insisting she “dress her age.” jlo/Instagram Lopez has continued to flaunt her fit physique in bathing suits, plunging gowns and more. jlo/Instagram “I do laugh at [the comments],” she said during a January show as part of her Las Vegas residency. “Why is she always dressed that way? … Why’s she always naked? “If you had this booty, you’d be naked too!” the dancer continued with a shimmy. Jennifer, who was in a barely-there fringe ensemble at the time, frequently flaunts her killer physique in bikinis, red carpet gowns and more. Community Guidelines Welcome to the Page Six Community!
