You know how celebrities are always asked about their beauty secrets? And you know how they usually rattle off a bunch of expensive products with exotic ingredients? Yeah, not JLo.

In an interview with UsWeekly, Jennifer Lopez revealed her number one beauty trick, and it鈥檚 not what we expected.

At 46, the musician-slash-actress-slash-businesswoman has a ton of beauty products at her disposal, but what she doesn鈥檛 have is caffeine. 鈥淭hat really wrecks your skin as you get older,鈥 Lopez told the mag. That means no coffee, no Iced Tea, no Red Bull (is that still a thing?).

Obviously, the mogul has her reasons. As Extra Crispy鈥檚 Kate Welsh notes, too much caffeine can be dehydrating and even 鈥渁ctivate stress hormones, which affect your skin鈥檚 oil production.鈥 Translation: zit city.

Lopez doesn鈥檛 just ditch the coffee, though. She also shies away from drinking and smoking too.

Considering the fact that she has two trainers 鈥 one on each coast 鈥 she probably doesn鈥檛 have much time for those vices anyway.

#ShadesOfBlue is a KO tonight at 10pm on NBC!

Lopez鈥檚 twins, seven-year-olds Emme and Maximilian, play a big part in her own diet. 鈥淲e eat a lot of green vegetables, asparagus, Brussels sprouts, broccoli, and kale,鈥 she told Us Weekly. And when she kicks off her morning with her kids at 6:30am, she鈥檚 usually well rested. Apparently, she aims for a solid 8-10 hours of sleep. (Don鈥檛 we all.)

Between recording new music, running her empire, raising her twins, and yes, dating baseball legend Alex Rodriguez, it鈥檚 shocking she can keep it all together without a single Americano. Color us impressed, but make no mistake: We鈥檙e not quitting our Starbucks addiction just yet.
