Kelly Rutherford is feeling the financial pinch thanks to her ongoing bitter custody battle with ex-husband Daniel Giersch.

The Gossip Girl star has blown through all her savings and her situation has become so dire that she has been forced to file for bankruptcy TMZ is reporting.

As previously revealed, Rutherford, 44, lost primary custody last year of son Hermes, 6, and daughter, Helena, 3, to her German-born ex, who now lives in Monaco, France, after he was forced to leave the U.S. following visa issues.

Rutherford's bankruptcy documents reveal she has spent a whopping $1.5 million on legal fees so far as she battles her ex in court.

"I've spent every penny," she said. "Every penny from Gossip Girl, my pension, my stocks has been spent fighting for my children."
