The Navy are just mad coz Leona shaded the fuck out of Rihanna and called her out for stealing her song form Calvin Harris. Leona LOVE Beyonce and clearly respects her. Now, as much as i like Leona, i know damn well she's no match vocally for Beyonce. Beyonce's vocal power alone would overwhelmed her. Plus Beyonce is more of a complete vocal package than Leona
