Expectant mom Tori Spelling, 38, was involved in a car accident on Monday with her two kids, Liam, 4, and Stella, 2, also in the vehicle. The Oxygen reality star blames the overzealous media for the crash, and expressed her frustration on Twitter, explaining how the accident occurred.

"Paparazzi chased me w/the kids 2school. I was trying to get away from him and had a pretty big accident," she tweeted. "Took down the whole wall of school. He thn STILL got out to try to get pics," she said. "Wht will it take? Someone dying for paparazzi to stop?"

The former Beverly Hills, 90210 star was also concerned about any impact the accident might have had on her unborn child. "Going to dr now to check on baby. I think its just shock."

Spelling and husband Dean McDermott, 44, are expecting their new baby this fall, but they have decided to put off finding out the baby's gender, according to Us Magazine. "We have one of each, so it will be a traditional surprise on the day."
