Renee calls it quits after just four months

BRIDGET Jones is untying the knot.

Renee Zellweger, who played the lovelorn Brit in Bridget Jones's Diary, and country music star Kenny Chesney will have their four-month-old marriage annulled, Chesney's publicist, Holly Gleason, and Zellweger's Los Angeles-based publicist Nanci Ryder, said.

In court papers filed on Wednesday, Zellweger listed "fraud" as the reason for the break-up but did not elaborate.
