Alessandra Ambrosio and Adriana Lima put on a Valentine's Day

With Valentine's Day upon us, it's the perfect time for the Victoria's Secret's models to start promoting their summer range.

The girls spent the afternoon posing on a Malibu rooftop as they modelled the Bombshell summer line yesterday.

Lily Aldridge showed off her womanly curves in a black polka dot bikini, which uplifted her figure.
