How are Lourdes and Bahja Rodriguez sisters?

Reginea and Bahja are not sisters. Bahja's little sister is Lourdes Rodriguez (Aka Lo Lo). Bahja and Lourdes's parents are Shamra Rodriguez and Jonathan while Reginea's parents are Dwayne and Toya Carter (yes people her father is Lil Wayne & sadly, no her parents are no longer married. Her mother is married to someone else... If you whatched the last episode of Toya then you'll know who she is married to).
