Rihanna Neck Mark: Was Someone Kissing the Singer’s Body?

Rihanna was in London Tuesday (Feb. 21), partying the night away at London nightclub Mahiki Bar, celebrating her 2012 BRIT Awards win earlier that day for International Female Solo Artist -- the second year in a row she earned the trophy.

As she was spotted leaving the venue, dressed in a bright yellow dress and oversized violet shades, the 'Birthday Cake' songstress appeared with a mysterious red mark on the right side of her neck. Paparazzi snapped excessive photos of the star as she departed, which can be seen in the video below, but the 24-year-old kept hush about the mark.

Could it be lipstick from another woman nuzzling at her neck or paint left over from her 'We Found Love' performance at the BRIT Awards? The Bajan singer was splattered with several different colors while rocking the stage.
