Kate Bosworth is placing the blame for her once painfully bony figure on her breakup with Orlando Bloom, MSN Entertainment reports.

In an interview with Harper’s Bazaar (via Australia’s Daily Telegraph), she says the implosion of their romance after four years together left her so stressed out she had no appetite, resulting in her thin form and prompting headlines questioning her health.

“It was my first very difficult breakup with someone I loved deeply and no matter how much I ate, it didn’t matter,” says the actress, who began dating model James Rousseau not long after she and Bloom parted ways.

“I hold all my emotions in the pit of my stomach, so it became difficult to eat. I remember going to a nutritionist and asking, ‘Do I have a parasite?’ ” Bosworth says.
