When Beyonce sings “put a ring on it” some guys take her seriously, very seriously. That’s the way it seemed Monday night at BankAtlantic Center in Sunrise, Florida where Beyonce thrilled a sold out crowd.

Just one night after winning the BET award for Best Female R&B Video of the Year for “Single Ladies (Put A Ring On It)” Sasha Fierce was all the way across the country putting on an energetic show that proves why she’s one of today’s top performers. And while that’s no surprise to her fans, there was one surprise when well into the show she was singing her hit “Put a Ring On It” and suddenly stopped. The stage lights went out until Beyonce said, “I need a light” and she was illuminated with a spotlight.
