Kate Upton & Alexandra Daddario Dish on Zac Efron's Abs

The YH Studio gets a double-dose of Stunning when Kate Upton & Alexandra Daddario stop by to scoop us on their comedy 'The Layover'! They tell us how they were able to translate their off-screen chemistry on-screen, plus they discuss the importance of comfort (physical and emotional) when wearing a bikini on-camera and the all-important topic of Zac Efron's abs!
