There is to be another addition to the wave of celebrity christenings taking place in Hollywood, it has been revealed.

According to media reports, Nicole Kidman, who is expecting her first child in June with singer Keith Urban, is planning to have her baby baptised in a Catholic church, with George Clooney named as the godfather.

"Nicole asked George to be her baby's godfather and he said 'yes'," a source told the Mirror. "They are great friends and she can think of no one more perfect for the job."

Speaking to People magazine earlier in the year, 46-year-old Clooney had commented how good Nicole would be as a mother.

Clooney, star of Ocean's Thirteen, recently denied various media reports claiming he and girlfriend-of-eight-months Sarah Larson had wedding ideas.

"There is not truth to any element of the story," a representative told Us magazine.
