It's actress Sophia Bush, best known for playing Brooke Davis from 'One Tree Hill!'

You might have also recognized her as Beth, the promiscuous vegan from 2006's 'John Tucker Must Die.' Who could forget the scene when she was the "slut in truck?"

She's also appeared in television shows such as 'Nip/Tuck,' 'Sabrina, the Teenage Witch,' 'MythBusters' and 'Punk'd.'

In January 2014, she started playing Detective Erin Lindsay on 'Chicago P.D.,' though it wouldn't take a detective to see why we're smitten with her.
