India, Jan. 3 -- Singer Jennifer Lopez had the perfect response to age-shaming trolls during the opening night of her Las Vegas residency, Up All Night, on December 30. The 56-year-old addressed online comments questioning her bold outfits and why she doesn't "dress her age." Speaking candidly on stage, Lopez said she has been in the industry long enough to not let criticism bother her. She added that she sometimes finds the comments amusing. "I do laugh at some of the things sometimes, because they do say funny things too," Lopez shared. Quoting trolls directly, she said, "Why she always dressed that way? Why don't she dress her age? Why she always naked?" before delivering her crowd-pleasing comeback: "If you had this booty, you'd be naked too." For the show, she wore a series of glamorous, skin-baring looks, including fringe minidresses and a lace catsuit. Up All Night marks her return to Las Vegas after her earlier hit residency, proving that confidence and style know no age limit.HTC...
