"He thn STILL got out to try to get pics. 10 school moms chased him away," she added. "Wht will it take? Someone dying for paparazzi to stop? Going to dr now to check on baby. I think its just shock."

"Tori is really shaken up but she and the kids are doing fine," her rep told People magazine. "She's going to the doctor for a checkup."

LAPD spokeswoman Officer Rosario Herrera told E! News, "She hit a curb near the school and no one was hurt. "There will be no further investigation." Herrera added that Spelling did not hit a wall of the school (TMZ has a photo that shows some damage to a small wall near a driveway).

Spelling and husband Dean McDermott are parents to son Liam, 4, and daughter Stella, 2. Their third child is due in the fall.
