Last night in Las Vegas Beyoncé performed at a private event for a pretty penny. Rumor has it she pocketed a few million from the mini concert event! Fans FREAKED out when Beyoncé came out to surprise them. Fans shared many pictures and even a snippet of Beyoncé singing her hit song, Crazy In Love! With a performance like this we can all look forward for Beyoncé to bring it even harder for husband Jay Z’s Tidal charity show later in the month!
