A Hungry Marilyn Monroe Butchers ‘Happy Birthday’ in Snickers’ Super Bowl Teaser

She's America's original sweetheart. But when she's hungry, Marilyn Monroe takes a turn for the worse. That's according to Snickers' new Super Bowl ad teaser, in which she reprises her iconic "Happy Birthday" serenade—to celebrate the Super Bowl's 50th birthday—but with quite the husky vocal. 

Check out the teaser here: 

"Since we're kicking-off the '50' celebration of one of the world's most iconic events, it seemed only fitting to cast Marilyn Monroe, a Hollywood icon with global appeal, to help us celebrate," says Snickers brand director Allison Miazga-Bedrick. "But this is just a small glimpse of what America should expect from Snickers on Super Bowl Sunday. As always, the ad will feature a funny surprise that we're confident will satisfy fans hungry for a laugh."

Snickers confirmed the Super Bowl spot continues the brand's "You're Not You When You're Hungry" positioning, which launched with the Betty White spot on the 2010 Super Bowl. The 30-second spot, from BBDO New York, will air in the first quarter of the Feb. 7 telecast.

Last year's Super Bowl spot from Snickers, starring Danny Trejo and Steve Buscemi in a Brady Bunch parody, was a big hit—and was named the second best ad of 2015 by Adweek.

Monroe originally sang "Happy Birthday, Mr. President" for President John F. Kennedy on May 19, 1962—10 days before his 45th birthday.
