George Clooney has reportedly changed his mind about becoming a father.

The 50-year-old actor has been vocal in the past about never wanting to get married again and fatherhood not being on his list of priorities.

But he is said to be totally in love with his 32-year-old girlfriend Stacy Keibler and is warming to the idea of starting a family together.

"Stacy is completely head over heels in love with him, and she knew going into the relationship that he wasn't likely to marry her," a source told In Touch.

"But she is really ready to have a child and feels that George would make the perfect father."

A friend told the publication that the loved up twosome had "the talk" recently where they discussed where their relationship was going. The Oscar winner was apparently the one to address the idea of having a baby.

"George brought it up first, but Stacy thinks it's a good idea," the insider added.

"George is constantly telling her how perfect she is for him in every way."

The Hollywood heartthrob's 11-year-old The Descendants co-star recently joked that "he wouldn't be the best as a father" after he let her eat seven bowls of ice cream on set.
