After an exciting birthday weekend, Kaley Cuoco kept things low-key when she stepped out with fiancé Karl Cook on Sunday. Shortly after announcing their engagement [1], the Big Bang Theory [2] actress and professional equestrian [3] ran a few errands around LA. They even proved they have the same taste in style by sporting similar hats. Aside from flashing the cameras a big smile as she made her way to her car, Kaley also gave us another glimpse of her gorgeous pear-shaped diamond ring [4] as she held her phone in her left hand. We're sure there are bound to be even more sweet moments [5] between the couple as they plan their upcoming nuptials.
