Britney Spears Hits St. James to Work Out

Energy Fitness & Wellness in St. James had a special, unexpected guest come in to work out Tuesday, pop star Britney Spears.

"I was training someone on the floor and she walked in," said Daniel Moreno, co-owner of Energy. "Her fiance and her fiance's dad came in, I used to train her fiance's dad ... they worked out for about an hour, she was on the treadmill and then on the freeweights and stuff."

Moreno said Spears came in during a downtime for the gym, and whatever members were in the gym let the pop star work out uninterupted. And while the staff was excited to see Spears, they let her work out on her own.

"Everybody was on their best behavior," Moreno said with a laugh.
