First Lady Michelle Obama on “Late Show With David Letterman” (CBS)

The First Lady will appear on the show, taped live in Los Angeles on Saturday, to honor country pop singer Taylor Swift with the Big Help Award. The prize — given to Michelle Obama herself in 2010 — honors people who try to make the world a better place.

“We are honored that First Lady Michelle Obama, a past recepient of the Big Help Award, will be presenting this formidable and inspiring artist with this much deserved honor,” said Nickelodeon Group executive vice president Marva Smalls.

Swift will be honored for raising money to benefit those suffering from natural disasters, the announcement added, including turning one of her tour rehearsals into a charity benefit.

This is the second time Obama will be on Nickelodeon this year — the First Lady stopped by “iCarly” to play herself on an episode earlier this year.
