Tori Spelling has been involved in a car crash.

The pregnant star - who is currently expecting her third child with husband Dean McDermott - revealed she was involved in a "pretty big accident" after a member of the paparazzi chased her vehicle while she was taking children Liam, four, and Stella, two, to school.

Writing on her twitter page, she said: "Paparazzi chased me w/the kids 2school. I was trying to get away from him and had a pretty big accident. Took down whole wall of school. He thn STILL got out to try to get pics.(sic)"

While a number of fellow mothers eventually chased the photographer away, Tori immediately went to the doctors to check on the health of her unborn baby.

She added: "10 school moms chased him away. Wht will it take? Someone dying for paparazzi to stop? Going to dr now to check on baby. I think its just shock.(sic)."

Tori - the daughter of late TV and film producer Aaron Spelling - recently admitted while she already has her "perfect family", she is always keen to add to her brood.

She said: "We have our perfect family - a little boy and now a girl, so we're blessed. But we love having babies so I will have more."
