George Clooney has denied the rumours that he will be a godfather to the new royal baby, suggesting his hands are already full with children of his own.
Speaking on the red carpet to US show Extra, he said: "Everybody loves their rumours. It's not true."
He added: "You don't want me to be a godparent of anybody. I'm barely a parent at this point.
Clooney, 58, who has twins with his wife Amal, also suggested that he was too busy with his own kids saying: "They're good. Now... When I'm left alone with them it's a nightmare."
The Hollywood actor also shares a birthday with Archie, who was born on Monday and jokingly said: "It's kind of irritating, if you think about it, cause I've already had to split it [his birthday] with Orson Welles, Sigmund Freud, and now this comes in.
"I'm moving down the line very quickly."
George and Amal Clooney are good friends with Meghan Markle and were just some of the star studded names that attended their wedding in Windsor last May.
Odds for the Clooneys to be the godparents of the newest addition to the Royal Family were as low as 6/1 among some bookmakers.

There are also rumours that the Beckhams may be asked to be godparents, as well as tennis legend Serena Williams and US chat show host Oprah Winfrey.
However, bookies show that stylist Jessica Mulroney, who is a close friend of the Duchess of Sussex, is the clear favourite, at 1/14.
The Duke and Duchess of Sussex presented their newborn to the world on Wednesday, and revealed his name, Archie Harrison Mountbatten-Windsor, shortly after he met the Queen.
