Ex-'90210' Star Vanessa Marcil Files for Divorce

Former "90210" star Vanessa Marcil has filed for divorce, TMZ has learned.

Marcil -- also known for her role as Brenda on "General Hospital" -- filed the docs against her husband "CSI:NY" actor Carmine Giovinazzo in L.A. County Superior Court, citing "irreconcilable differences." The couple was married in 2010. They have no children.

Marcil wants Carmine to pay her attorney's fees. She's also asking the court to award her spousal support.

FYI -- Marcil famously dated her "90210" co-star Brian Austin Green from 1999-2003. They had a son named Kassius together in 2002.

Megan Fox is now the kid's babysitter.
