Which lips do YOU think are most attractive? Scientists reveal the most desirable pout - so, do you agree?

From Angelina Jolie to Megan Fox, many celebrities are known for their luscious lips. But what exactly does the perfect pout look like? A new study has revealed the answer - and it's bad news for fans of lip fillers. Scientists from the American University of Beirut showed 200 people AI-generated pictures of a woman, whose lips had been adjusted in various ways. An analysis of their preferences revealed that the perfect pout features an upper-to-lower lip ratio (U/L) of between 0.618:1 and 1:1.
