Rihanna earned four number-one singles during the year — three as a solo artist and one as featured guest on Eminem's "Love the Way You Lie" — the first time a female artist has achieved this accomplishment in a single calendar year. She also became the female artist with the fifth most number-one singles, scoring her sixth, seventh, eighth, and ninth number-one singles during the year. Katy Perry, Eminem, Kesha, and Bruno Mars also each scored multiple number-one singles during the year, with Katy Perry scoring three consecutive number-one singles — a feat last done by R&B singer Monica eleven years earlier.
