George Clooney's sister, Adelia Zeidler, doesn't believe rumors that her little brother is gay.

Adelia Zeidler, who goes by Ada, is quoted by UK's the Daily Mail as saying that her brother is wedded to work and isn't likely to marry or start a family anytime soon.

“I think he decided that in his life he could have the career or he could have a family and so when he decided to go full bore into the acting, that was where his focus was going to be,” Zeidler said.

Zeidler, a widow who raised two children on her own after the sudden death of her husband in 2004, still lives in the city where she and her brother grew up: Augusta, Kentucky.

“[H]e probably will not get married,” she said.

Clooney divorced actress Talia Balsam in 1993. He is currently dating Stacy Keibler.

On those gay rumors which have hounded Clooney for years, Zeidler added: “Yes that's quite ridiculous, we don't even listen when people say things like that anyone.”
