Rihanna has scored a fifth week at the top of the U.S. pop charts - no one can touch her "Rude Boy". The R&B star has fought off B.o.B's "Nothin' on You" and Train's "Hey, Soul Sister", which stay put at two and three, respectively, on the chart.
Taio Cruz's "Break Your Heart" and "In My Head" by Jason DeRulo round out the new top five. Jack Johnson scores the week's highest debut on the Hot 100 - his "You and Your Heart" enters the chart at 20.
Rihanna is currently preparing her Last Girl on Earth tour which will be supported by Ke$ha. She will begin the gig on July 2 and has received drum lesson from Travis Barker for rehearsal of the traveling show. In between the tour, she will perform for Lilith Fair, joining Sarah McLachlan, Emmylou Harris, Loretta Lynn, Beth Orton, Erykah Badu, Mary J. Blige and Sheryl Crow.
