Sarah Michelle Gellar reacts to being sued by McDonald's over Burger King commercial at 5 years old

'Buffy the Vampire Slayer' actress found herself in fast-food war in 1980s

Sarah Michelle Gellar was sandwiched in the middle of a food fight at the age of 5.

The now 45-year-old actress spoke out about the time she received heat from McDonald’s for starring in a Burger King commercial.

"This is really funny. This big campaign that I did for Burger King and I was 5," Gellar remembered during an interview with BuzzFeed UK. 

"I was the first person to say another competitor's name in a job. … McDonald's turned around … sued the advertising agency, Burger King and me at 5."

In the 1980s commercial, a young Gellar is seen sitting on a bench in purple overalls with her hair in two pigtails wrapped in white bows.

"Do I look 20% smaller to you? I must to McDonald’s. When I order a regular burger at McDonald’s, they make it with 20% less meat than Burger King. Unbelievable!" Gellar says in the commercial.

"Luckily, I know a perfect way to show McDonald’s how I feel, I go to Burger King."

Despite being in the middle of a food war, Gellar recalled not eating a lot of fast food when she was younger. But she admitted that while she was filming the commercial, she did have a hankering for it.

"When we were there, I just wanted a burger. I was so excited because my mom said I could have the burger," she told the media outlet.

Gellar said she also discovered how the fast-food giant made their burgers look so appetizing.

"What I learned on that day is that when they make the burgers for commercials, they glue each seed on it to make it look all perfect and beautiful … then they shellac it, and they paint it. You guys, TV is not real," she said.

McDonald’s did not immediately respond to Fox News Digital’s request for comment.
