Kaley Cuoco knows how to spread some serious holiday cheer!
The Big Bang Theory star surprised her parents with a new Lexus RX350 on Monday, a generous gift they did not expect, judging by their shocked reactions.
Cuoco, 28, and her fiancé, Ryan Sweeting, looked on with smiles as mom and pop Cuoco checked out the deep blue crossover, complete with a giant red bow. (The car costs about $40,000.)
This will be the couple’s first holiday season together but there’s plenty more celebrating to come – they’re set to tie the knot on New Year’s Eve.
