Today is Valentine's day, and as a tribute to this holiday, we are bringing you the hottest pop stars wearing the signature color of love, red. The color red has always represented fiery elements like heat, love and passion, so naturally pop stars wear the color considering they are some of those most passionate and hottest people walking on this planet.

In these pictures of red hot pop stars, see throwback pictures of stars like Shakira, who wore a red leather jumpsuit to the Latin Grammys in 2000. Also, fans can see singers like Katy Perry vamping up their look by wearing the color, like when she rocked a Jessica Rabbit-esque outfit while performing at the 'VH1 Divas Salute the Troops.' Take a look at these pictures of pop singers in red and tell us which performer looks best in the color.
