Usher apparently uses bike riding to keep up with his fitness regiment. The 31-year-old R&B singer was spotted out in West Hollywood Sunday (Jun 13) getting some afternoon bicycling in with his personal trainer.

Meanwhile, Usher told the Associated Press last week that he knew “OMG” would be a worldwide hit, but he had no idea his own kids would take so well to the hit single!

“I knew ‘OMG’ would have “incredible energy” but did I know that my children would love it at 1 and 2? I only hoped.”

Usher is father to 2-year-old Usher Raymond V (aka “Cinco”) and 1-year-old Naviyd Ely Raymond. He divorced their mother, Tameka Foster, last year.
