Traffic police in Sussex spotted the busty brunette lose control of the large vehicle and drift into another lane on a busy road, causing two oncoming cars to swerve out of the way.
Cops claimed the 32 year old, also known as Jordan, had been using her cell phone for up to three seconds when the incident took place on 19 February (10).
Price denied the charge, insisting she had not been distracted by her mobile phone, and blamed her bad road skills on being a "typical woman driver".
She told the court, "I'm just not used to a lorry that big. I was probably a bit scared because it was on a motorway. I don't remember veering but it is quite difficult."
Price had been on her way to Euro Disney in Paris, France with friends and family, including four children, when she was pulled over by cops.
She was cited for the phone violation and allowed to continue her journey.
But a jury at Mid Sussex Magistrates' Court found Price guilty of not being in proper control of a vehicle during a hearing on Tuesday (28Sep10) and she was ordered to pay the fine, in addition to legal costs amounting to $975 (£650).
She also had three penalty points added to her driver's licence.
