Country singer Kenny Chesney has conceded he rushed into his short-lived marriage with Renee Zellweger.

The musician married Zellweger in a surprise ceremony in the Virgin Islands in May (05), but his actress wife filed legal papers to have their marriage annulled just four months later (SEP05).

Neither Chesney nor Zellweger have spoken about why their marriage failed, but the country star suggests their courtship should have been longer.

He says, "What was that old song: 'We got married in a fever, hotter than a pepper sprout.'"
