After being reminded of the name of Obama's anti-childhood obesity campaign, Miranda stated confidently, "It would be called, 'Let's Move!'"

The pair had some time to work on a potential Broadway collaboration — Obama was on hand Sunday to honor Miranda at the Smithsonian's National Portrait Gallery's gala in Washington.

The third biennial American Portrait Gala recognized the Broadway pro and five other honorees whose "accomplishments have made an impact on the nation's shared history, development and culture."

Miranda, 39, called Obama his "dream presenter" for the black-tie gathering. The ex-executive mansion resident was an early champion of the composer. Miranda first publicly performed a song from "Hamilton" — which went on to be a 2015 Broadway smash hit — at the White House in 2009.

"That early advocacy, I can't ever repay her for that," Miranda, who's part of Obama's 2020 "When We All Vote" get-out-the-vote campaign, told journalists.
