Revving up the crowd of luminaries with a rendition of Queen’s “We Will Rock You” and “We are the Champions,” Lambert got the Oscars off to an explosive start.

Queen was the focus of the Oscar-nominated film "Bohemian Rhapsody," starring Rami Malek, who won the best actor Academy Award for his performance as Freddie Mercury in the movie.

The opening number got the awards crowd cheering and pumping their fists.

Lambert first rose to fame as a runner-up on the popular “American Idol” singing competition in 2009. He auditioned for the show with the song -- wait for it -- “Bohemian Rhapsody.”
