Miranda Lambertand Carrie Underwood are sitting pretty atop Billboard's Hot Country Songschart with their sexy summer smash "Somethin' Bad." Propelled by significant gains in sales, streams and airplay, the track leaped from number-18 to number-one last week.

How rare is a female collaboration in that top spot? It's only happened twice before in the past 50 years.  Dolly Parton,Linda Ronstadt and Emmylou Harris shared a number-one in 1987 with their rendition of "To Know Him Is to Love Him." Reba McEntire and Linda Davis had the second with 1993's "Does He Love You."
