AceShowbiz - Teenage actress Emma Roberts had to buy her second car just months after passing her driving test - after a "scary" accident wrecked the star's first purchase. Julia Roberts' 18-year-old niece obtained her driver's license on her second attempt in 2009 and celebrated by treating herself to her own vehicle.

But a bad accident left her car beyond repair and although the incident has made her a more careful driver, Roberts admits she suffers from nerves every time she gets behind the wheel of her new planet-friendly Toyota Prius. She explains, "I got in a really bad accident which was scary. But I'm now a much more cautious driver because of it."

"Everyone says, 'Were you on your iPod or your phone?' And actually, I wasn't. I really wasn't. Long story short, my car was in the shop for four or five months and that was sad. I had a big car too it was the scariest thing ever."
