Rugby superstar Sonny Bill Williams has welcomed his second child into the world.

The All Black tweeted a picture of himself and his second daughter on Sunday morning, with a message saying she was a healthy girl.

He and his wife, Alana Raffie, have named their new daughter Aisha, a sister to Imaan, who was born in 2014.

“Aisha Williams, our gift from the most high came into this world struggling, but alhamdulillah after a long night she’s improving,” he said.
