The makers have confirmed that the 41-year-old musician will join Katy Perry on the judging table, reported Variety.
While the third spot is yet to be locked down, a source from the reality singing TV series' production unit said that "Idol" will stick with a panel of three and not four judges.
Other artists who are being considered for the panel included Charlie Puth and Keith Urban.
The show is slated to premiere in early March, launching its debut episode shortly after the Oscars, which will be held on March 4.
