Sabrina Carpenter just revealed her "The Eras Tour" makeup routine on TikTok, and fans are taking notes.

The 24-year-old singer has gained momentum for not only releasing catchy tracks like "Feather" and "Nonsense" but also securing a spot as an opening act on Taylor Swift's monumental tour. It's no surprise that people are excited about Carpenter's makeup routine.

In a "Get Ready With Me" video posted via TikTok Sunday, Carpenter shared her step-by-step makeup routine while backstage at Swift's "Eras Tour" concert in Buenos Aires, Argentina. Evidently, the breakout pop star does her own makeup.

Carpenter started her video with her face already prepped with a matte foundation and warm bronzer. She also sported a shimmery eyeshadow look and short-winged eyeliner, while her brows were perfectly filled-in.

She first held up a fluffy brush, identifed by Teen Vogue as the Makeup by Mario Surreal Foundation F4 Brush, and dipped it into the blush she chose for her look: Makeup by Mario's Soft Pop Plumping Blush Veil.

Carpenter accentuated her features by delicately applying the blush to her cheeks and strategically dusting a hint onto the bridge of her nose. This subtle touch gave her a sun-kissed appearance.

Ever heard of the blush theory? According to beauty experts and influencers, blush can change a person's face shape depending on how it is applied.

Beauty content creator Klaudia Sydor, known as @klaudiasyd on TikTok, shared a video illustrating the transformative effects of various blush application techniques.

According to the influencer, to achieve a natural flush, concentrate the blush on the higher regions of the cheeks. For a sun-kissed appearance akin to Carpenter's, lightly dab a small amount of blush onto the nose and blend it in a subtle "W" shape spanning both cheeks. To craft a sculpted look, strategically apply blush to areas typically contoured on the face.

Meanwhile, after Carpenter's blush demonstration, she moved on to her lip routine, which she began by revealing her choice of lip liner: the Nyx Slim Lip Pencil. Although the application wasn't shown, her lips appeared lined with a neutral brown hue in the next clip.

Transitioning seamlessly, she held up and applied two different shades of the Nyx Fat Oil Lip Drip: Follow Back and Scrollin'. These products worked their magic, leaving her lips with a glazed finish, adding a delightful glossy touch to her makeup look.

Finally, she locked in her makeup with setting spray to ensure her look remained flawless for her stage performance.

Carpenter recently announced the upcoming release of her Christmas EP, "Fruitcake," scheduled to launch Friday.

Following this, she's gearing up to join Swift again for a series of shows in Australia and Singapore in February and
