Country star Kenny Chesney's ex-fiancee has come forward to clear up rumours the singer is gay following his shock split from wife of four months Renee Zellweger.

MANDY WEALS, who was engaged to Chesney for three years, admits she's puzzled as to why Zellweger has accused her ex of fraud in divorce papers - but she insists people are jumping to conclusions.

The 36-year-old, who is now married to a Tennessee developer, says, "Kenny's 100 per cent macho and definitely not gay. He loves women. I should know."

Chesney's publicist HOLLY GLEASON admits Zellweger's fraud claims have made her really busy.

She says, "The number one question everyone's been asking me after Renee declared the marriage a fraud is, 'Is he gay?' He's not."
