N SYNC - CHASEZ DEFENDS CHEATING SONG

Former 'N SYNC star JC CHASEZ fears fans will read too much into his new single UNTIL YESTERDAY, which follows the story of a guy who discovers his girlfriend is expecting another man's baby. Chasez wrote the song with former bandmate JUSTIN TIMBERLAKE, who also produced the tune, but insists neither he nor his pop star pal have experienced such an adultery dilemma. He tells MTV News, "It's not autobiographical. We just wanted to push the limits. "It just seems like everybody has heard a break-up song a hundred times or a thousand times. And they've heard, 'I don't like you anymore' a thousand times, or 'You make me sick, you used me, blah blah blah.' "We thought we'd pepper it with some drama and it made it an interesting song."
