They're here! George and Amal Clooney's baby twins have arrived.

They’re the celebrity twins the whole world has been waiting for (well, besides Beyoncé…) and now they are finally here.

Yep, Amal and George Clooney have welcomed their twin babies into the world.

The couple, who were married in 2014, welcomed a baby boy and girl into their lives on Tuesday morning, US time.

And, surprisingly, they have given them two very ‘normal’ names: Ella and Alexander.

“This morning Amal and George welcomed Ella and Alexander Clooney into their lives,” new father-of-two George told PEOPLE Magazine in a statement.

“Ella, Alexander and Amal are all healthy, happy and doing fine. George is sedated and should recover in a few days.”

Another source close to the family - which literally just doubled in size - said the pair are "very, very happy".

"George is going to be a great father of twins," they said.

The actor hinted last week that the arrival of the babies was imminent, pulling out of the Aurora Prize event that he co-founded.

"If I came and my wife had twins while I was away I could never come home," he told the crowd via video link.

With George's charm, acting ability and good looks and Amal's intelligence and compassion, these two bubs have no doubt won the genetic lottery and will probably grow up to be Oscar-winning rocket scientists.

We should have seen the fact that the new bubs were going to be given relatively 'normal' names coming: during Amal's pregnancy, George joked that his wife had definitely shut down any talk of naming their twins after his tequila brand, which is also owned by Cindy Crawford's husband, Rande Gerber.

"My wife says I can't name them Casa and Amigos," the actor joked.

"That's the one thing I'm not allowed to do."

While the new parents had never officially confirmed they were having a girl and a boy, Cindy Crawford let it slip when she posted a photo of the onesies she got for the twins, one with pink lettering and the other with blue lettering.

Ella and Alexander are the first children for both the 56-year-old actor and the 39-year-old human rights lawyer, who wed in Venice, Italy in September 2014.

The pair had only been dating for seven months when George popped the question, much to the surprise of Amal who took several minutes to accept.

"We just sat there and finally I said, 'Listen, I'm 52 and I’ve been on my knee now for about 28 minutes, so I gotta get an answer out of this or I'm going to throw a hip out. I might not be able to stand back up!'" Clooney told Charlie Rose on breakfast show CBS This Morning in May 2015.

It was confirmed in February that George and Amal were expecting twins after US chat show host, Julie Chen told The Talk viewers "Beyoncé is not the only superstar expecting twins".
