Wiz Khalifa demands joint custody of son from Amber Rose

Wiz Khalifa has demanded a joint custody of his 1-year-old son Sebastian after facing a divorce petition from wife Amber Rose.

According to TMZ.com, the joint custody would act as advantage for the rapper because there was a presumption that joint custody was in the best interests of a child.

Rose is the one who demanded a prenup and she's getting a lump sum payment of 1 million dollars.
