In honor of Super Bowl 50, Snickers is treating the game to an honor usually reserved for presidents and major Hollywood stars – a "happy birthday" serenade from Marilyn Monroe.

Well, almost.

The latest addition to the "You're Not You When You're Hungry" campaign features a hungry Marilyn Monroe preparing to reprise her iconic performance. But when she steps up to the mic and starts to sing, a gravelly, much less seductive voice comes out.

The 30-second spot will air during the first quarter of Super Bowl 50 on Feb. 7. Like all "You're Not You When You're Hungry" commercials, it reminds fans that Snickers always satisfies hunger.

The commercial continues Snickers' history of advertising during the Super Bowl. The brand debuted its first "You're Not You When You're Hungry" commercial, featuring Betty White, during Super Bowl XLIV 2010. Since then the campaign has featured dozens of other celebrities and athletes.

"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 Allison Miazga-Bedrick, director, Snickers brand. "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."
