Natascha McElhone's mounting fear after hubby died suddenly leaving her with nothing but a bun in the oven!

The Californication beauty was shocked when her husband plastic surgeon Martin Kelly, suddenly collapsed and died of a heart attack on the steps of their London home last summer.

McElhone who was pregnant with the couple's third child soon discovered Kelly had not left a will and she found herself nearly penniless.

"I was finishing (Californication) and I had a lot of debt," Natascha admitted.

"Martin's estate was zero - there was nothing in it because he had reinvested all his money. I was the one who paid for everything else.

"It was unbelievably stressful" she confessed. 

"I'm amazed that my pregnancy was fine - nothing went wrong."
