George and Amal Clooney welcome newborn twins

George Clooney has become a dad for the first time.

The actor's wife Amal Clooney gave birth to the couple's twins on Tuesday morning, George's publicist Stan Rosenfield has confirmed.

The couple have named their children Ella and Alexander and according to Rosenfield mother and babies are all “happy, healthy and doing fine".

He said in a statement: "This morning Amal and George welcomed Ella and Alexander Clooney into their lives. Ella, Alexander and Amal are all healthy, happy and doing fine."

As for 56-year-old George, Rosenfield joked that he is "sedated and should recover in a few days".

The fact the couple have already confirmed the names of the tots will come as a surprise as The Descendants star recently claimed he and Amal, 39, had not yet decided on what their monikers would be.

He said: "No we haven't picked out any names and I'll tell you why ... Because I've had friends pick out names around their parents and then it becomes ... Whatever name you pick they're like, 'Oh, I don't like that. That guy's a prime minister' 'Can't name her Susan. You remember your Aunt Susan?'

"[But] can you believe it?! Yeah, [I'm] even happier [than before]. I didn't know that we'd have kids. I was very happy that we were going to get married and then [a pregnancy] seemed like the next step."

Amal reportedly gave birth in a luxurious £8,500 suite.

The human rights lawyer and her husband George Clooney are said to have welcomed their twins - Alexander and Ella - into the world in the comfort of a luxurious private suite in the Kensington Wing at London's Chelsea and Westminster Hospital.

The suite can cost up to £8,520 but those who stay in these special rooms can expect no less than midwife support, one to one, as well as 24 hour care by a consultant.
