Less than a week after Renee Zellweger filed for an annulment from Kenny Chesney after a four-month marriage, he said he's doing well but that "there have been better times."

Chesney wants his fans to know he'll "be OK."

Chesney spoke with Country Weekly magazine Monday at his home outside Nashville. He said he hit everything hard this year -- a big tour, a record to finish, and, of course, "something new" in his personal life. He said it's been a huge year that "really ended up being too much."

Chesney is the reigning Country Music Association entertainer of the year, and his CD "When the Sun Goes Down" was named album of the year.

He finished his tour and said he's tired now, but added that by next year he'll be excited to get back to it. He also said that next year the focus will be on his music again and not on what he calls "the sideshow."

In court papers filed Sept. 14, Zellweger listed "fraud" as the reason for the breakup.

Zellweger released a statement Friday saying that "fraud" was "simply legal language and not a reflection of Kenny's character."

"I would personally be very grateful for your support in refraining from drawing derogatory, hurtful, sensationalized or untrue conclusions," Zellweger said. "We hope to experience this transition as privately as possible."

In a statement released Friday by Chesney, the country music singer said, "This is an incredibly sad time. ... I just hope everyone can respect the privacy that I know Renee has already asked for."

Zellweger and Chesney married in a small, surprise Caribbean island ceremony in May after first meeting Jan. 15 at a benefit for tsunami victims.

Zellweger is known for her roles in such films as "Jerry Maguire," "Bridget Jones's Diary" and "Chicago."

She won a Best Supporting Actress Oscar for her role in "Cold Mountain" in 2004.

Zellweger is 36. Chesney is 37. It was the first time either of them had been married.
