“Oh hey, Chrissy,” theMaroon 5frontman — who’s performing the Super Bowl LIII halftime show — says, and theLip Sync Battlehost, 33, responds, “Must we do this every time?”

Legend captioned his post, “Tiny audience… big impact.”

The tune in the commercial was so catchy that fans naturally assumed the “All of Me” singer wrote it — but, as it turns out, it’s actually Teigen’s masterpiece.

The cookbook author revealed the news in response to a fan’s tweet, which read, “Ugh, John could make BILLIONS on jingles. Between this andHeadband of the Day, he’ll be in my head all day…”

“I WROTE IT,” Teigen responded in all caps.

Legend previously told PEOPLEthat he and wife have been singing the “Stinky Booty Song” — which he claimed he created — to Luna ever since she was just 1 or 2 months old.

“She still loves the song even though she’s potty-trained,” he said. “We’re using it on Miles now.”

When it comesto being on diaper duty, Legend told PEOPLE that he and the model have split it pretty evenly with their kids.

“It’s just whoever is able to do it at that time,” he said. “It has never been a thing where it’s like, ‘You have to do it or I have to do it.’ It’s like, ‘Okay, I have himright now and his diaper needs changing, I smell it, I’m going to change him.’ I’ve always been like that, and never felt any hesitancy to do it.”

“I had never changed a diaper before Luna, but I learned quickly,” Legend explained. “It’s not hard — just do it. I think us having dogs has made it easier to deal with the whole poop of it all. Onceyou get used to poop, you’renot too squeamish about anything.”

Super Bowl 53, which pits the Los Angeles Rams against the New England Patriots, is airing live from Atlanta on CBS.
