Kristin Cavallari got candid about social media "red flags" she's seen while dating men. "Following girls [is] not a big deal," Cavallari, 39, said during a Tuesday, March 24, episode of her "Let's Be Honest" podcast. "Don't stress it. But the 'liking' of the pictures is a bit of a red flag." She continued, "In a perfect world, ladies, we would get into a relationship and our guy would unfollow every random girl that they don't know." Cavallari also advised her fans not to tell their men they "can't" follow someone.
