Kenny Chesney's publicists are fighting claims the country star has reunited with his ex-wife Renee Zellweger after the couple were spotted together in a Tennessee cafe.

The pair have been spotted dining together many times since splitting last year (05), but aides insist they're just trying to be good friends.

Chesney's publicist HOLLY GLEASON says, "They're friends... They're two nice people who don't choose to live in public."

Chesney and Zellweger's four-month marriage was annulled last month (DEC05).
