We think he Hollywood do it – installing George as the favourite name (6/1) for his first-born.

That’s level with Brad, in tribute to Clooney’s best pal Brad Pitt, while another long-time friend, Matt Damon, could be honoured (11/1) after he was the first person George confided in.

For girls, Lisa (9/1) is a leading contender, after his British model ex Lisa Snowdon.

Presidents are often a popular inspiration for names, with Barack (25/1) understandably deemed more likely than Donald (66/1) to be the chosen moniker.

While the Clooneys are just the latest high-profile figures to reveal that they’ll be adding twins to the family – following Beyonce and Jay-Z’s pregnancy announcement last week, and Madonna’s adoption of twin girls this week.

Reportedly pregnant Irina Shayk and Bradley Cooper are the bookies favourites (9/1) to join the ‘twin’ crowd – followed by Cheryl Cole and Liam Payne (20/1) and Prince Harry and Meghan Markle (22/1).

Spokesman Paddy Power said: “So gorgeous George’s next headline role could be as the lead in Ocean’s Four, as Amal is set to give birth to twins.

“I like the idea of the Clooneys naming their child after great pal Brad Pitt but, if they’re stuck, they could always just look to his filmography and refer to the kids as The Descendants.”
