Jessica Alba is a much stricter parent than her own mother and father.

The 30-year-old actress - who has two daughters, Honor, three, and six-month-old Haven, with husband Cash Warren - admits she is harder on her kids than her ''cool and laid back'' mum Catherine and dad Mark Alba were for her.

She said: ''I did have that dreaded moment when my daughter decided that every answer I gave her wasn't a good one and she kept saying, 'But why mommy? But why mommy?', and I was like, 'Because I said so'. And I thought, 'Oh God, I'm that mum, I'm my mum'.

''My parents did use 'because I said so' and they were not strict. They were fun and cool and laid back and a way better time than me.''

Jessica admits she was such a ''super bad'' child she once took her dad's car and drove to a fast food restaurant at the age of 14.

Speaking on 'Jimmy Kimmel Live', she added: ''I got good grades and I was going to Bible study all the time.

''I wasn't bad. But I rebelled, I guess. Like one time when I was fourteen or thirteen or something, I took my dad's Ford Probe to Jack in the Box. I took side streets. It was a car full of girls. We were bumping Sublime. I was a super bad kid.''
