Carrie Underwood – Age 38

A bare-faced Carrie Underwood is typical for fans of the American Idol winner. Just in April 2021, she shared a selfie after a sweat session, highlighting her post-workout glow. In recent years, the Jesus Take The Wheel hitmaker has prioritized her health, and proof that it has been paying off are her rock-hard abs.

The country singer gets a bit of help from an app called Fit52, which she created with her trainer Eve Overland. Underwood might be using this time to also prepare for her Las Vegas residency. Apart from her, Katy Perry and Luke Bryan have gotten spots in Sin City.
