Thanks to her feature on Eminem's latest single 'Love the Way You Lie,' from his 'Recovery' album, Rihanna has cemented herself as one of the four female artists with the the most No. 1 hits on the Pop Songs airplay chart. Ri-Ri has officially tied Mariah Carey -- who first held down the the number one spot -- scoring six No. 1 singles on the Nielsen charts. Beyonce and Lady Gaga caught up to Carey back in March, when their single 'Telephone' pushed them both to six No. 1 songs each.

Four of Rihanna's chart toppers are her original songs, in addition to two features on T.I. and Eminem's tracks. Rihanna's No.1 appearances are as follows: 'SOS' (May 2006), 'Take a Bow' (July 2008), 'Disturbia' (October 2008), T.I.'s 'Live Your Life' (Dec 2008), 'Rude Boy' (May 2010) and 'Love the Way You Lie' in August 2010. The pop songstress recently expanded her horizons to acting, when she officially signed on for a role in Universal's upcoming 2012 film 'Battleship.' She was also nominated for an Emmy Award earlier this year after appearing on the 'Saturday Night Live' skit 'Shy Ronnie.'
