Chesney, 37, and Zellweger, 36, wed in a surprise May (05) ceremony on the Caribbean island of St John in the Virgin Islands after meeting at the Concert Of Hope tsunami relief show in January (05).
But last week (ends16SEP05), the couple shocked Hollywood circles when it was announced that Zellweger is seeking to have the marriage annulled after just four months as husband and wife.
And while Chesney won't elaborate on the circumstances surrounding the split.
He says in a statement: "This is an incredibly sad time... I just hope everyone can respect the privacy that I know Renee has already asked for."
