The 43-year-old actor played Kevin McCallister in the iconic Christmas film franchise, with the first film released in 1990 and the sequel in 1992. O’Hara starred in the films as his mother Kate.
Introducing Culkin at the Walk of Fame ceremony last week, O’Hara was pictured embracing her on-screen son and touching his face affectionately as she spoke about the beloved star.
“Home Alone was, is and always will be a beloved sensation,” she said.
“The reason families all over the world can’t let a year go by without watching and loving Home Alone together is of Macaulay Culkin.”
She looked back at Culkin’s “perfect” performance in the films, acknowledging that while he “worked really hard” he also made “acting look like the most natural thing in the world to do.”
O’Hara paid tribute to Culkin’s “sweet and twisted, yet totally relatable sense of humour”.
“I believe that you have to possess a certain quality, a gift that dear John Hughes obviously recognised. It’s a sign of intelligence in a child and key to surviving life at any age and you have brought that sense of humour to everything you have ever done.”
“You so deserve your star on the Hollywood Walk of Fame. And thank you for including me, your fake mom who left you home alone not once, but twice, to share in this happy occasion. I’m so proud of you.”
Culkin was seen hugging O’Hara and wiping away tears as he took to the podium for his acceptance speech, during which he thanked his partner Brenda Song, who joined him there along with their sons, 2-year-old Dakota and Carson, 7 months.
