The 44-year-old actress, renowned for her quirky dress sense, turned heads at a Los Angeles Awards ceremony last week with her curvy look.
Speaking at the red carpet she revealed what she was wearing.
"Today I'm wearing huge breasts. No, it's a corset. They're still real - if you get a proper corset," the Daily Mail quoted her as saying.
She said it fooled people into thinking her breasts are bigger than they are.
"It's amazing what a corset will do," the actress told US Weekly.
"I'm not all that well-endowed. These are my Golden Globes. Who needs Golden Globes when you've got these?" she added. (ANI)
