Carrie Underwood Reveals What She Looks Like Without Makeup at the Gym

No makeup? No problem! Carrie Underwood showed off her radiant face without a stitch of makeup while working out.

The "Dirty Laundry" singer, 33, kept it real with fans during her gym outing, where she rocked the striped Women's Drape Side Double Layer Tank Top ($55, from her own Calia by Carrie Underwood collection, naturally, and short shorts. "I'm a sweaty mess, but I'm a sweaty mess in an adorable tank!" she captioned the Instagram snap on Thursday, August 25, with a #nomakeup hashtag.

It's a rare made-under look for the country powerhouse, who's almost always flawlessly done up — complete with a bold smoky eye — on and off Instagram. Nevertheless, fans enjoyed seeing Underwood in her element, giving the pic more than 80,000 likes and adding comments like "Real is beautiful!"

The American Idol alumna has been particularly open via social media as of late. Last month, she took to Instagram to wish her husband of six years, Mike Fisher, a happy anniversary with an especially heartfelt note.

"Six years ago today, I said 'I do,' to this handsome fella," she captioned a photo with her husband, with whom she shares 17-month-old son Isaiah. "I meant it then and I mean it now. God put us together and continues to bless our marriage. I couldn't imagine this life without you, @mfisher1212 I am thankful for these past six years together (and, of course, for our beautiful son, Isaiah) and I look forward to spending the rest of our lives in love."

Equally sweet, Fisher replied by posting a snap from their wedding day with a note: "6 years ago today we were married. Time sure does fly when you're having fun and you marry up. I'm very grateful to have an amazing wife and mother by my side!"
