Does Cameron get love advice from his sister?

When it comes to girls, you'd think Cameron Dallas would go to his roomie, Nash Grier, or another Vine guy in his crew for pointers. But it turns out that when Cam's heart is hurting, there's only one person he looks to. "I go to my sister for girl advice," Cam tells J-14 exclusively. "Most of the time I share the situation and just want her input. Then, I usually go with my gut." Being the sweetie that he is, Cam returns the favor for his sis, Sierra. "I've always been protective over her," he reveals.
