LOS ANGELES — Never known to do things by halves, George and Amal Clooney, one of the most glamorous power couples in the world, on Tuesday announced they had become parents at last, to twins.

"This morning Amal and George welcomed Ella and Alexander Clooney into their lives," said a publicist for the 56-year-old star of Gravity and Ocean’s 11.

"Ella, Alexander and Amal are all healthy, happy and doing fine," added publicist Stan Rosenfield, joking that "George is sedated and should recover in a few days."

Amal’s parents, who are Lebanese, said they were elated by the news and that everything had gone smoothly.

"We are over the moon," said Amal’s mother Baria, speaking from London where she was in hospital with her daughter. "It was a beautiful delivery. The babies are beautiful and are doing well."

Amal’s father Ramzi Alamuddin, reached in Beirut, said he had spoken with his daughter and son-in-law after the twins’ birth and hoped to travel to London soon to meet them.

"They are in great health, all is perfect. I am very happy for them," he said, predicting the couple "will be great parents."

Oscar-winner Clooney was once one of Hollywood’s hottest bachelors before falling for the stunning 39-year-old Lebanese-British human rights barrister. They married in 2014 in Venice, in a lavish wedding attended by A-listers and closely covered by media outlets from around the globe.

News of the twins’ birth set social media abuzz on Tuesday with many commenting on the classic names picked for the baby boy and girl.

"Amal Clooney gives birth to twins with beautiful, average names," read one tweet.

"I usually eschew celebrity news, but George and Amal Clooney having twins (boy & girl) seems like good news for humanity on some tiny level," another twitter user noted.

"Welcome to the world, Ella and Alexander Clooney," said US talk show host Ellen DeGeneres. "Congratulations, George and Amal, or as I’m now calling you, Ocean’s Four." — AFP
