Canadian crooner Michael Bublé takes his bubly Super Bowl LIII campaign to the people on Friday’s “The Ellen DeGeneres Show” as he poses as a cashier at a grocery store.

The Grammy-winning singer upsells the PepsiCo sparkling water to unsuspecting customers in a hilarious hidden camera prank, all while DeGeneres tells him what to say through an earpiece.

In a completely unplanned moment, “Modern Family” star Eric Stonestreet enters the store, leading to a rather awkward interaction between the two celebrities. Bublé later admits that he thought DeGeneres was “reverse punking” him when Stonestreet walked up to his counter.

The highlight though involves shopper Teny Abedian, who falls for the prank. The unaware shopper is utterly baffled as Bublé makes “beep-boop” noises while he scans her items and tries stealing her credit card details.

For being such a good sport, DeGeneres invites Abedian onto the show, along with Stonestreet, who says he feels like he “just crashed a party.” DeGeneres then surprises Abedian with $1,000, courtesy of bubly.

Bublé stars in the first-ever Super Bowl ad from bubly, where he sits on the floor at a grocery store using a marker to change the “y” on every can of bubly to an “e”.
