NBA star Carmelo Anthony and his wife actress LaLa Anthony had decided to separate after seven years of marriage and nearly 20 years together.

Apparently there’s a potential outside baby in the mix…

Insiders tell TMZ the other woman works at a strip club in New York, and that she’s claiming to be six and a half months pregnant with Carmelo’s baby.

The source also admits the marriage has been rocky for a while and there’s virtually NO chance of reconciliation.
