Gilbert Arenas has won a battle against Laura Govan, but he hasn't won the war -- a judge just ordered her to pay him A LOT of money in one of their lawsuits against each other.
As we previously reported, Arenas sued his baby mama for libel after she allegedly wrote a nasty email about how he gave her STDs ... and then leaked it to various media outlets.
The ex-NBA star claimed the email humiliated him and affected his ability to work on his app without distraction.
