Rihanna's found a rather comfortable spot heating up the Billboard charts  this week. The Bajan beatuy's latest single 'Only Girl in the World,' tops the Digital Songs charts with 249,000 first week downloads marking her eight single to debut on Digital Songs, and her sixth to debut at No. 1, the most reached in each category by an artists since 2005, the year the chart launched. The song jumped 72 spots on the Billboard's Hot 100 chart, and currently sits at No. 3 on the singles chart after premiering three weeks ago.

Ironically, the 22-year-old's ex, Chris Brown also saw major chart success with his single 'Deuces' continues to top the R&B/Hip-hop singles chart for the third week in a row. If the two have to battle it out on the charts that'll be an interesting competition, if nothing else. Both are planning on dropping new albums, although Rihanna's is due out this November and Brown has yet to give a release date.
True to form, Ri-Ri's reign doesn't stop there. Eminem's track 'Love the Way You Lie,' which she is featured on, is at No. 2 on the Hot 100 charts, nipping at the heels of singer Bruno Mars who currently holds the No. 1 position. Mars, whose recent arrest may be increasing his popularity, shot to the top of the Hot 100 charts with his debut single 'Just the Way You Are.' As previously reported, the 23-year-old was arrested for drug possession Sunday (September 19) at the Hard Rock Hotel in Las Vegas after being confronted by security in the hotel's bathroom. He was later taken into custody for what is believed to have been 2.6 grams of the drug. With his chart topping single, off his upcoming solo effort 'Doowops & Hooligans,' which drops October 5, the Mars becomes the third male artist this year to have a debut single land in the top spot.
