NEW YORK - Usher says he knew his latest song would be a hit in the clubs, but he didn't think that would translate into his own home.
The singer said this week that he knew "OMG" would have "incredible energy" but adds: "Did I know that my children would love it at 1 and 2? I only hoped."
The thumping dance tune is produced by will.i.am and is his ninth No. 1 single. It's from his gold-selling album "Raymond v. Raymond."
The 31-year-old is the father of 2-year-old Usher Raymond V and 1-year-old Naviyd Ely Raymond. He divorced their mother, Tameka Foster, last year.
Usher credited will.i.am for the song's success. He said the Black Eyed Peas leader always "keeps his finger on the pulse of where the world is and what they're listening."
