Days before the 2016 Grammy Awards, Adele took to the stage at The Wiltern in Los Angeles to perform a secret concert that was packed with celebrities.

Her friend and "The Late Late Show" host James Corden introduced the record-breaking singer before she opened the Feb. 12 concert with her chart-topping smash hit "Hello," according to Billboard. The show was filled with tons of classic Adele hits like "Rolling in the Deep," "Set Fire to the Rain" and "Someone Like You," as well as new material off her latest album "25."

With the concert being in Los Angeles, there were plenty of celebrity fans in the audience including Jennifer Lawrence, Tom Hanks, Emma Stone, Woody Harrelson, Rebel Wilson, Katy Perry and Orlando Bloom, according to Entertainment Weekly.

"I haven't played in L.A. for years," Adele told the crowd. "Sorry if it was a pain in the ass getting the tickets...I would have [charged] less, but my record label is paying for this." 

The concert at The Wiltern comes just weeks before Adele is set to take off on her "25" world tour on Feb. 29 in Belfast, according to Rolling Stone.

At the Los Angeles show, the singer told the crowd that the 15-song setlist and stage design were made especially for the secret show and did not mean her tour would sound or look the same.
