Jackman's followers shared their love for the actor and his mother in the comments. One follower wrote that McNeil "must be a proud mum," while another wished Jackman and his mother a "relaxing" time together.

The actor has been open about the challenges he and his mother have faced throughout the years, and even revealed that they were estranged at one point in time.

Jackman told Parade in 2015 that his mother left him when he was just 8 years old.

"My anger didn't really surface until I was 12 or 13. It was triggered because my parents were going to get reconciled and didn't," he explained, per People. "All those years I'd been holding out hope that they would."

And in a 2011 interview with the Sun, Jackman said his mother left their family because she had "undiagnosed postnatal depression," something he'd discovered much later.

But even though Jackman was furious about his mother's absence, he said he eventually came to understand why she left, reportedly telling the Sun that they "have definitely made our peace, which is important."

Jackman said he and his mother now have a "good relationship," per People. The two have been photographed attending premieres and red carpet events together in recent years.
