Hugh Jackman and Sutton Foster are reportedly taking their relationship to the next level — and the news has “shattered” his estranged wife, Deborra-Lee Furness.

The former “Music Man” co-stars are now living together in the “Deadpool & Wolverine” star’s New York City penthouse, a source told Australian news outlet New Idea.

“They’re inseparable,” the insider said. “[Sutton is] slowly migrating her things over to Hugh’s place.”

The source further claimed that Furness is “shattered knowing Sutton is making the penthouse her own — the place she poured her soul into.”

Furness is also said to be worried that the actor is moving too fast in his new relationship.

“She wants him to be happy — he deserves it and so do the kids, but Hugh’s completely green when it comes to dating. She’s concerned he’s leaping into living with someone else way too soon,” the insider added.

Meanwhile, another friend said, “It’s almost unreal [for Deborra] seeing Sutton reap the rewards of all those years of her supporting Hugh.”

Reps for Furness, Foster and Jackman did not immediately respond to Page Six’s requests for comment.

Furness, 69, reportedly filed for divorce from the “X-Men” star, 56, last Friday after the pair reached an agreement behind the scenes.

“There was some back and forth regarding this financial agreement but, in the end, [Deborra] got what she believed she deserved. Both are coming out of this financially secure,” a source told the Daily Mail Tuesday.

“They have worked out the details in advance and everything is ironed out in terms of a settlement, alimony and the expenses for the future of their children.”

Furness and Jackman — who share two adopted kids: son Oscar, 25, and daughter Ava, 19 — are said to be “fully committed to being the best parents that they can be.”

On Tuesday, Furness addressed the breakdown of their marriage in a statement to the Daily Mail, saying, “My heart and compassion goes out to everyone who has traversed the traumatic journey of betrayal. It’s a profound wound that cuts deep, however I believe in a higher power and that God/the universe, whatever you relate to as your guidance, is always working FOR us.”

She continued, “This belief has helped me navigate the breakdown of an almost three-decade marriage. I have gained much knowledge and wisdom through this experience. Even when we are presented with apparent adversity, it is leading us to our greatest good, our true purpose.

“It can hurt, but in the long run, returning to yourself and living within your own integrity, values and boundaries is liberation and freedom.”

The Australian actors announced they were calling it quits in September 2023 after 27 years of marriage.

Soon after, rumors began circulating claiming Jackman had cheated on Furness with Foster.

“They are 100 percent together and are in love and want to spend the rest of their lives together,” one insider said.

Jackman and Foster — who filed to divorce her second husband Ted Griffin in October 2024 — have been spotted packing on the PDA and holding hands since going public.
