Actress Kaley Cuoco treated her parents to an early Christmas present on Monday (23Dec13) by presenting them with a brand new car.

The Big Bang Theory star had the Lexus Suv (Sports Utility Vehicle) delivered to her family home in Sherman Oaks, California just before the festive holiday, complete with a big red bow, and gave mum Layne and dad Gary the shock of their lives as they stepped outside their house and laid eyes on the pricey present.

Photos of the big surprise show Cuoco's mother with her mouth open in awe, while her father, holding a glass of champagne, is depicted smiling as he points at the new car in disbelief.

Cuoco has plenty to celebrate this Christmas - she recently became engaged to tennis star Ryan Sweeting.
