The 'Booty' singer snapped a quick pic yesterday (10 November) while heading out in the car, adding the caption: "Another Car selfie... Happy Monday."
The 45-year-old (we can't believe it either!) looked totally gorgeous in her snap, showcasing a clear, glowing and oh-so-radiant complexion with perfectly-defined cheekbones.
Her make-up looked flawless yet still fresh and dewy, and she proved she opted for naturally groomed brows and a very subtle wash of brown eyeshadow along with lashings of mascara on her peepers.
What a yummy mummy!
And while we're used to seeing J-Lo with a dab of nude gloss on her pout, this time she amped things up in the lippy department with a bright pillar-box red hue.
We heart red lippy because even the simplest outfit can be effortlessly glammed up with a slick of rouge.
Want to get in on the act too? Check out MAC Lipstick in Ruby Woo, £15.50 - it's a cult product with a huge celebrity following, including Rihanna (who even created her own limited edition version of the lippy - RiRi Woo).
It is matte so it can be a tad drying, so slick on a lip balm beforehand to help up the hydration.
Prefer a glossy formula? We can't get enough of Clarins Joli Rouge Lipstick in Clarins Red, £19, which boasts a buttery soft, super-conditioning formula delivering a gorgeous shiny finish for a plumped-up pout.
