Hollywood actress Jessica Biel says she is paranoid about being bankrupt as she often doesn't know when her next pay cheque will come.

She fears she will run out of money because she has no fixed source of income, reports contactmusic.com.

Biel, who is dating pop star Justin Timberlake, stars in 'The A-Team'. But she admits she worries about paying her bills because she doesn't receive movie offers too often.

'Since I was so young when I started (acting) I didn't think about it (money). I just liked it, it was fun. But as I got older and started to become an adult and then had to get a car and have to pay for insurance and all those things...it's a huge worry,' said Biel.

'For example, I haven't worked at all this year. I haven't made a film so I haven't had a pay cheque and I won't do anything until September and I don't know if I'll do anything after.

'It's always up in the air constantly. My life is very much a question mark when the next pay cheque is coming in,' she added.
