AceShowbiz - At the Egyptian Theatre Hollywood premiere of his new documentary "Will & Harper", Will Ferrell experienced a wardrobe malfunction, but his sons were there to save the day.

While Ferrell was giving an interview, Magnus, 20, and Mattias, 17, noticed the tails of their father's suit jacket were still stitched together. They ducked behind him to separate the loose threads.

In a humorous video shared on a TikTok page, the Ferrell brothers can be seen running up behind their dad as he stands next to co-star Harper Steele. Together, they pulled and lifted the back of the navy blue suit jacket. Ferrell joked that his kids were like "primates" as they adjusted his outfit.

The actor's wife, Viveca Paulin, was also present. The couple has another son, Axel, 14, who was not in attendance.

After the wardrobe mishap was resolved, the family posed for photos together. Ferrell wore a navy blue suit, light blue shirt, and blue tie, while Mattias opted for a navy button-down and blue slacks. Magnus wore a white shirt, open blazer, brown belt, and gold chain necklace.

"Will & Harper" follows Will Ferrell and his friend Harper Steele on a road trip after she comes out as transgender. The film features appearances from former "Saturday Night Live" cast members Seth Meyers, Tina Fey and Kristen Wiig. It will be released in select theaters and on Netflix on September 27.
