Pop diva Britney Spears has revealed that she keeps her lips looking perfect by using a special beauty regime involving aluminium foil.
The Womanizer singer reportedly uses cool strips of the metallic cooking aid to give her lips an instant pick-me-up when she is feeling tired, reports femalefirst.co.uk.
"To keep her lips looking perky and fresh, her make-up artist takes a sheet from a stockpile of frozen foil in his freezer, pokes a hole in it so Britney can breath through her mouth and smoothes it over her face," said a source.
The regime apparently helps reduce puffiness and swelling, leaving Britney with a perfect pout.
Britney, 27, is not the only star with an unusual oral beauty regime.
Jennifer Aniston apparently uses a homemade lip scrub containing sugar and water to banish flaky skin, while Angelina Jolie swears by a $4 lip balm.
A source said of the Tomb Raider beauty: "Angelina stockpiles the lip butter to preserve her to-die-for pout. She likes it because it also helps to freshen your breath and Angelina hates chewing gum."
