The 'No Air' singer proved she's not afraid of going bare-faced in her snap, flaunting glowing skin without a hint of foundation or blusher in sight.
Jordin's deep chocolate peepers sparkled sans mascara, and she showed off full brows and a perfect lipstick-free pout.
She also encouraged her fans to ditch the slap too, captioning her pic: "Good morning! Be fearless! Show me your makeup free selfies! Tag #loveyourselfie & I'll retweet! :)"
Jordin took part in the TODAY show's 'Love Your Selfie' series, which saw her shun the war paint for a whole week.
She also wrote an essay about her experience for TODAY.com, saying she feels "completely comfortable" going au naturel.
In her essay, Jordin said: "As women, I know it gets tough when you become used to a certain look or routine. But we should realise that we should feel comfortable and confident in who we are with or without. When I see other women without makeup, my first thought usually is, "You go girl!" I also think about how it's great for them to let their skin breathe."
Here's to hoping more stars follow in her footsteps!
