During the outdoor Dec. 4 ceremony, Wilson will sing as will Patti LaBelle, pop duo Nico & Vinz, singer and actor Ne-Yo, Steve Miller, and country singer Chely Wright with pop group Fifth Harmony.
The Canadian vocal group the Tenors will be singing holiday songs too.
The president will flip the switch on thousands of LED lights on the existing blue spruce in what's called the People's Park.
It is surrounded by the Christmas Pageant of Peace, is a ring of smaller decorated trees that represent each U.S. state, territory and district.
And here's a cool interactive for techie young girls: They'll be able to create their own pattern of holiday lights for the Pageant of Peace trees through a computer coding project sponsored by Google.
The "Made With the Code" initiative aims to spark interest in math, science and technology among young girls. The online design project for holiday lights begins Tuesday.
