How to get this hairstyle without heat?

Does anyone know Shay Mitchell? She plays Emily Fields on the tv show Pretty Little Liars? Well I adore her hairstyle and wonder if I can get it overnight? or real fast in the morning? For those of you who don’t know her, heres a picture of the hair I want to achieve:
