Model Penny Lancaster was definitely showing what made Rod Stewart such a walkover in a new line of lingerie aimed at spicing up Valentine’s Day for love-struck couples.

The 31-year-old model, whose boyfriend is the 57-year-old singer, was promoting the Stiletto Collection from lingerie brand Ultimo.

The limited edition collection consists of a plunge bra, corset and thong in stiletto shoe print.
