The famous muppet provided festive cheer by the bucketloads as the US leader and his family lit up the National Christmas Tree in the grounds of the White House.
Giving a lively reading of Twas The Night before Christmas together, Michelle and Kermit hit it off particularly well.
"You can call me Michelle," the mom-in-chief told her green friend.
"That's really nice of you. I have to call Miss Piggy 'Your Majesty'," he quipped.
The whole family, including Michelle's mum Marian, gathered round the button to light up the tree, which is one of 38 that have been decorated for Christmas in and around the mansion.
At 26 feet, the New Jersey tree is a little smaller than its predecessor. This was the 40-ft Colorado Blue Spruce which had grown in the grounds for 48 years before being snapped in half by strong winds a few months ago.
"This is the new tree. I know it's not quite as big as the old tree.
"But it's going to take time to grow. But we are going to fill it up with spirit and start the new tradition right now," said the American leader.
The crowds were also entertained by performances from the Black Eyed Peas and Ellie Goulding.
