"A big security-looking guy walked in and asked us what time we closed," said Pilicer. "I'm thinking he's going to come in with maybe a couple of other people and then all of a sudden a couple of people wearing hoodies do start trickling in and one woman comes up and asks me where the bathroom is and I look up and it's freaking Beyonce."

"There's no way we could have planned it. No one had any idea. I didn't even know anything," said Pilicer.

"Beyonce follows the sounds, she just walks right in, and there are two girls sitting and one of their friends had fallen asleep on the lounge chair...I'm standing there watching this whole thing and the other people in their party started walking in and cracking up because they were singing Beyonce."

Although, they didn't quite immediately recognize who either of them were, the two girls invited Beyonce and Kelly in. "They start dancing together, but they have no idea who it is, said Pilicer. "And all of a sudden one of the girls looks at kelly and says, "Oh, you look like Kelly Rowland" and then she looks at Beyonce and goes "Oh my god!"
