President and Michelle Obama have decorated the White House for their last Christmas as the first couple, and they didn't hold back at all for the 94th annual National Christmas Tree Lighting Ceremony. One of the president's favorite rappers, Chance the Rapper, performed for a crowd that included Sasha Obama, who lip synced like a pro to "Sunday Candy" while Chance performed.

The president and first lady also seemed to enjoy Chance's performance, but Sasha definitely stole the show by singing along from the audience, seeming to know each and every word. At one point during the song, Sasha looked to her right in the direction of her parents, who also seemed to be having a great time.

The president and Chance go way back. Obama recently told Sway in the Morning on Shade 45 that he's known Chance since he was a kid. "Chance I’ve known for years 'cause his dad was my state director when I was a senator in Illinois," the president said. "I first met Chance when he was eight years old."

Chance the Rapper has been to the White House three times in the last year, and since he is one of the president's faves you'd think he also would have been lip syncing right alongside his daughter, but the president seemed content just to sit back, relax, and enjoy a show with his family.
