Be careful what you wish for. You just might get it.

Sarah Marie Summer, a model with a bra size of "8M," is believed to hold the distinction of having Australia's largest (fake) breasts. But she says she wants to go even bigger.

"I want to look silly and I want to be huge," she told Australia's Women's Day. "They make people smile and that makes me happy, so that can't be a bad thing."

The 23-year-old says she was 17 when she had the first of her three breast enlargements, and has claimed she is "addicted to boob jobs." She said she has gone up 18 bra sizes.
