R&B singer Mariah Carey is on the verge of tying legendary British band the Beatles, for having the most chart-topping hits. The superstarâs newest single “Touch My Body” is poised to give her 18 No. 1 singles, which would tie her with the Fab Four. The song is the lead track on her latest album “E=MC2,” due to hit stores later this month. The 37-year-old songstress is currently tied with Elvis Presley for second place for top singles. Carey, the best-selling female singer of all time, showed off her new hit and slimmed-down body on NBC’s “Saturday Night Live” this weekend, sporting stilettos and a micro-miniskirt.
