Rihanna Gave Cara Delevingne Some Solid Advice

If this whole pop star/Dior campaign star gig doesn't work out, Rihanna could always fall back on her side business: A-list agony aunt and amateur life coach.  In a new interview with WSJ. Magazine, RiRi's pal Cara Delevingne revealed how the singer helped her deal after losing a coveted role in the upcoming Beach Boys film.  The model/actress admitted she was "heartbroken" about not getting the part, but a phone call to Rihanna put things right. “Everything happens for a reason," Rihanna told her friend. "You are going to call me back in a week or two and say, ‘You are right.’”   Obviously, RiRi knows best. As it happens, Delevingne soon landed the lead in Paper Towns, and has roles in Pan and Suicide Squad also coming up. The British beauty — rumored to have left a Cannes party this week to avoid an awkward run-in with ex Michelle Rodriguez — also shared her frustration with the industry. "It’s horrible living in a world where I’ll get a call from someone saying, ‘So-and-so says you were partying a lot and you were looking this way and you need to lose weight,’" she said. "It makes me so angry. If you don’t want to hire me, don’t hire me.”   Sounds like someone could use a hug and a spoonful of wisdom from RiRi. (Page Six)
