Is mary j blige and free from 106 and park sisters?

No, Free, (born Antoinette Marie Wright on February 7, 1968 in Dorchester, Massachusetts) and Mary J. Blige (born Mary Jane Blige on January 11, 1971 in Yonkers, New York) are not sisters, though they do have some shared history at BET.

When Free produced two special 106 & Park episodes they became the highest rated shows in BET's history.

Mary's Be Without You remained on BET's 106 & Park Countdown for 65 consecutive days!

Free left the show in 2005, and since July of 2006 Rocsi (born Raquel Roxanne Diaz on November 17, 1983 in Tegucigalpa, Honduras, Central America), and Terrence Jenkins (born April 21, 1982 in Queens, New York City) have hosted it.

On July 1, 2012 both announced that they will be leaving the show.
