Lego unveils the house from "Home Alone," a Christmas classic 1:19

(CNN) -- He's the kid left to fend for himself in everyone's favorite holiday comedy, and on Friday he got some Hollywood notoriety.

Macaulay Culkin, star of the '90s classics "Home Alone" and "Home Alone 2: Lost in New York," among many other titles, received a star on the Hollywood Walk of Fame this week. To congratulate him was his on-screen mother, Catherine O'Hara.

O'Hara, who in Chris Columbus and John Hughes' 1990 film realized he had left his son "Kevin" at home on a plane to France for Christmas, said Friday that the reason "Home Alone" was and is so beloved is Culkin.

"It's Macaulay's perfect performance as Kevin McAllister that gave us that little boy on an extraordinary adventure," he said.

"I know you worked really hard," O'Hara continued, "but you made acting seem like the most natural thing in the world."

As Culkin stood beside him, looking dapper in sunglasses and a black double-breasted suit, O'Hara became emotional as he called him "the most beloved thing."

He also touched on the overwhelming popularity of the films and how that sudden stardom might have been too much for Culkin, but credited his sense of humor with helping him persevere.

"It's a sign of intelligence in a child, and a key to surviving life at any age," O'Hara observed, adding, "From what I see, you've brought that sweet, yet twisted, relatable sense of humor to everything you've decided to do since 'Home Alone.'"

"Thank you for including me, your fake mother who left you home alone not once, but twice, to share this happy occasion," O'Hara concluded. "I'm so proud of you."

Friday's ceremony was also attended by Macaulay Culkin's partner, Brenda Song, siblings Rory Culkin and Quinn Culkin, and friends Paris Jackson and Seth Green. Culkin's "Party Monster" co-star Natasha Lyonne also gave a speech in honor of "Mac."
