Tori Spelling and her children were involved in a major fender-bender on Monday.
"Paparazzi chased me with the kids to school," Tori Tweeted. "I was trying to get away from him and had a pretty big accident."
She continued "I took down whole wall of school. He then still got out to try to get pics. Ten school moms chased him away," she added. "What will it take? Someone dying for paparazzi to stop? Going to doctor now to check on the baby. I think it's just shock."
Spelling, 38, and husband Dean McDermott, 44, have two children together: Stella, 2, and Liam, 4. Their third baby is due this October.
Taking down the wall of a school is a VERY big accident! When will the Paparazzi stop? Glad to hear Tori and the kids are doing well.
