Kate is a lovely American actress who has had some trend setting short hairstyles, but here she has long and wavy locks that cascade over one shoulder.
The other side is tucked back behind her. She has a side part and a swooped up bang that is long and brushed up and over. Her color has several shades of blonde from honey to light. This one comes from the  "Life Happens" Los Angeles Premiere where she is wearing a light yellow halter top with crystals.
