Katy Perry is a fan of a new range of lipstick that changes colour according to your mood. Her fiancé Russell Brand can tell if she’s feeling romantic just by looking.
The new lipstick – made by American firm Too Faced – is ideal for women who are too shy to take the initiative with their lovers.
A cosmetics industry insider said: “This is not likely to be a problem for Katy and Russell, but more confident couples can have a lot of fun with it.”
The Mood Swing Emotionally Activated Lip Gloss changes from clear to deep crimson by reacting with the wearer’s body chemistry.
The £12 cosmetic comes with a colour chart so men can tell what’s going on.A spokesman for the Sun said: “The colours change depending on your emotional state.”
But experts warn it could become an embarrassing way of letting secret crushes out of the bag. Mood Swing lipstick is available in the UK at Boots and Asos.com.
