Still, we have noticed a bit of a difference in the size of it this year, with the "Booty" crooner's bum looking smaller than it ever has before. So, what's the deal?
J.Lo hasn't addressed the booty-shrinking chatter just yet, but she did reveal she lost ten pounds recently by following a strict vegan diet and doing daily six-hour dance workouts.
"You got to work out, you got to watch what you eat. It's a job - you've got to buckle down," she told Us Weekly, adding, "I feel great mentally and physically!" The Parker star reportedly slimmed down to a size two from a size four by cutting out dairy, meat and gluten.
"I'm not an exercise fanatic," she continued. "I don't love it, but I do dance a lot for the shows, so that helps." She also doesn't drink alcohol. "I feel better when I'm in shape and taking care of myself. If you want other people to love you, you have to care about yourself first."
And it shows. J. Lo, who turns 45 next month, is looking better than ever.
