Renee Zellweger and Kenny Chesney have split - just four months after marrying in the Caribbean.

The couple shocked fans when they announced that they'd wed on 9 May (05) in a sunset ceremony on St John in the Virgin Islands before 35 close family and friends.

It was the first marriage for both.

No further details about the couple's split have been made available, but People magazine reports that they're having their marriage annulled.

Unfortunately for Zellweger, fellow Texan Dr Phil McGRAW's summer (05) prediction that her marriage to Chesney would last just four months has been proven right.

At the time, she hit back, "To come home from getting married and have that guy setting the betting table in Vegas at three months or four months or whatever it was... I'm not so worried about what Dr Phil thinks."

The couple met at the 15 January (05) Concert of Hope tsunami relief benefit, where Chesney sang and Zellweger took phone pledges.

The first public display of their romance occurred on 29 April (05), just a few weeks before their wedding, when COLD MOUNTAIN star Zellweger surprised Chesney in Jacksonville, Florida - bringing him a margarita onstage for his song WHEN THE SUN GOES DOWN and kissing him on the cheek.

One of Chesney's biggest hits is a song called YOU HAD ME FROM HELLO, a takeoff on the famous line from Zellweger's breakout 1996 movie role opposite Tom Cruise in Jerry Maguire.
