Mother and son bond

Despite it being more than three and a half decades since Home Alone released, the co-stars have continued to share a deep bond with one another.

During an appearance on Watch What Happens Live! In 2015, she revealed the two had a sweet reunion at an art opening.

“He was coming out and he went, ‘Mommy!’ and I said, ‘Baby’,” Catherine told host Andy Cohen.

He also confirmed that he called her “mom” each time her saw her, proving their bond was unmatched.

Macaulay told New York Times in 2024: “She opens up her arms – she goes, ‘Son’.”

On-screen reunion

The much-loved duo delighted fans back in 2024 when they reunited on-screen for a ad for Freedom Unlimited alongside .

Catherine was seen walking into a shopping mall before shouting out her iconic “KEVIN!” dialogue.

The co-stars shared a warm embrace, with Kevin joining in on the hug with the two.

Excited fans couldn’t believe their eyes as one gushed: “This is hysterical. I love these nostalgic commercials.”

Somebody else added: “So beautiful, a home alone reunion.”

Co-star chemistry

Macaulay and Catherine’s on-screen camaraderie translated off-screen, with many Home Alone fans believing they were actually mother and son in real life.

She recalled to Today in 2024: “A child came up to me, like, a little 8-year-old, in a mall. ‘Are you Kevin’s mom?’

“I said, ‘Well, yeah, I played Kevin’s mom in a movie, yes’.

‘Why did you leave him?’ ‘Sorry. It was in the script!’,” she remembered.

Speaking to PEOPLE back in 1990, when the film first released, Catherine described then 9-year-old Macaulay as ”a darling little guy who has been acting since he was 4, so he’s very professional.”

“He comes in knowing all his lines, knowing where to hit his marks — he even knows all the other actors’ lines.

“I expect he should become the head of the studio by the time he is 12,” she joked.
