Giselle Fernandez & Husband Split -- Newsflash: It's Over... And I'm RICH

Journalist and TV host Giselle Fernandez just lost 180 pounds ... by dumping her husband after 11 years of marriage ... and according to legal docs, she's quick to point out ... she makes a fortune.

52-year-old Fernandez filed for legal separation from business exec John Farrand on Friday, citing irreconcilable differences.

And this is interesting ... Giselle is NOT asking for spousal support, saying in her docs, "I was the breadwinner." Giselle claims she typically works 40 hours a week and earns an impressive $41,667 per month.

Other fun stuff -- Fernandez claims she spends $6,500 a month on rent and $2,000 on GROCERIES.

The couple was married at their Beverly Hills home back in November 2002. They have a 7-year-old daughter, and Giselle wants joint custody.

In addition to "Access Hollywood," Fernandez guest anchored for "CBS Early Show," "CBS Evening News," "NBC Today," "NBC Nightly News," and even appeared on "Dancing with the Stars" (she didn't last long).
