EXCLUSIVE
"CSI" star Jon Wellner has called it quits on his marriage after 7 years, and says it's time his wife gave up on her acting, got off her ass and started working.
According to the divorce docs ... Jon says his wife, Whitney Wellner, hasn't made it as an actress and probably never will ... he's asking the courts to force her into pulling down a full-time job.
Whitney lists her credits like "Save the Last Dance" -- released in 2001. She also got a guest gig on "CSI" last year, but he insinuates it was a case of nepotism.
Whitney fires back in her legal docs, saying he obviously thought she was good enough to appear on his show.
She's presumably gunning for spousal support, and it's gonna be hard for her to live without it. While she says he makes $20k an episode, she pulls in $12 a month in residuals.
Who knew they were still playing "Save the Last Dance"?
