Renee Zellweger has gained 10 pounds in a bid to find a new man. The 39-year-old actress - who is divorced from singer Kenny Chesney - has gone from a tiny U.K. size six to a slender size eight.

A source said: "Renee was worried her slim frame made her look gaunt, sickly and, worst of all, old. She is going to be 40 in six months and doesn't want to be single then."

Rumors have been circulating recently that country singer Kenny Chesney is engaged. The country superstar is shooting down the engagement report.

According to People.com, Chesney's rep said, "Kenny Chesney is not getting married. He's not engaged. He's not planning on being engaged any time in the near future. In fact, he was surprised by the news and isn't sure how or why anyone would've gotten that idea."

Kenny Chesney claims nothing about his marriage to Renee Zellweger made him happy.

The singer married 'Bridget Jones' Diary' star Renee in 2005 but the couple split just four months later.

Renee Zellweger doesn't want to have children.

The 'Leatherheads' actress - whose six-month marriage to country singer Kenny Chesney was annulled in December 2005 - has "no ambition" to be a mother, and would rather concentrate on enjoying her independence.
