Brian Austin Green just learned a $200,000 lesson … you snooze, you lose … ’cause a judge just threw out his lawsuit against baby mama Vanessa Marcil because he waited WAYYYY too long to file.
We broke the story … B.A.G. sued his baby mama/former “90210” co-star Marcil … claiming he began lending her money in 2000 … and when he came to collect the roughly $200k debt in 2011, she told him to pound sand.
But today, an L.A. County Superior Court judge ruled … Green had waited too damn long to pursue legal action against the mother of his 10-year-old son … and the statute of limitations had run out.
And it gets worse for Brian … ’cause the judge also told Marcil she can seek monetary sanctions from Green for what her lawyers called a “frivolous” lawsuit.
Bad day for Green … but he still gets to bang Megan Fox … so it’s probably a wash.
