"He’s spoken to Deb and they’ve seen each other. They speak pretty regularly," said an insider.

How did Hugh Jackman and Deborra-Lee Furness meet?

In 1995, Jackman and Deborra-Lee first met on the set of the Australian TV series 'Corelli'.

The 'Prisoners' actor had just begun his acting career after graduating from drama school. However, Deborra-Lee was already an established actress at the time.

The duo began dating and tied the knot less than a year later. Remembering his first meeting with his now estranged wife, Jackman said, "Deb, she was a big star…I get picked up, and Deb is in the front seat of the car. I’ll never forget," according to People.

"She took off her seatbelt and turned around and put out her hand and took off her sunglasses and said, 'Hi, I’m Deborra-Lee Furness, nice to meet you.' I remember thinking 'I like this girl,'" the actor recalled.
