With the DNA test a match, we're told lawyers for Knowles and Wright are in the final stages of negotiating a settlement for baby Nixon's child support.
Wright filed a paternity suit last October against Knowles -- who was temporarily ordered to pay $8,200 in monthly child support.
Wright claims she had an 18-month affair with Knowles.
As far as we know, nothing's tricky about Nixon .... so far.
An L.A. judge just ordered Knowles to pay $8,200 a month in child support, retroactive to February 1. Knowles must also pay 100% of uninsured medical costs.
Alexsandra Wright claims she had an 18-month relationship with Knowles and he's the baby daddy of Nixon -- born February 4.
Wright's lawyer, Neal Hersh, went to court today asking for support and the judge granted it.
But Knowles will take a DNA test March 1 ... and the long-term support issues hinge on the outcome.
It's interesting -- Knowles has not flat out denied he's the daddy. And in fact, he gave Alexsandra $10,000 in January to cover uninsured medical costs and baby stuff.
UPDATE: The Judge ordered Knowles to pay Wright $20,750 for the month of January.
