Victoria Beckham is best known for her pouting mouth expression with rumours that she rarely if ever smiles.

In fact her smile is quite sweet and childlike, although she does tend to temper it by keeping her lips closed or her teeth clenched edge-to-edge, implying inner tensions.

This suppressed smile can look like a short-fall gesture, as though she has the intention of smiling but without a spontaneous sense of real happiness.

Her closed-lip smile still looks pretty, but by keeping the top lip down she also creates muscle tension that thins the top lip leaving it less balanced and making her appear more secretive.
