Selena Gomez has a trick she uses when she applies mascara to her bottom lashes, and it involves an unexpected beauty tool.

The 29-year-old pop singer and actress turns to handy-dandy tweezers when she needs definition added to her bottom lashes.

She demonstrated the technique in a 43-second makeup tutorial she posted to TikTok for her cosmetics line, Rare Beauty.

The clip, which is set to the Patsy Cline’s song "Crazy," shows Gomez using the tip of a tweezer probe to collect mascara ink from a wand.

She then presses the tweezer probe together along sections of her bottom lash line – making sure to not smudge it under her eye.

Fox News Digital reached out to representatives of Gomez for comment.
