"I find it incomprehensible that LGBT citizens are being discriminated against in the state of Mississippi," the 56-year-old musician posted to his Instagram on Sunday night. "I cannot in good conscience perform in a state where certain people are being denied their civil rights due to their sexual orientation. Therefore I'm cancelling my April 14 show at the Mississippi Coast Coliseum."
The law takes effect in July, and allows businesses, individuals and religious organizations in Mississippi to deny service to LGBT individuals, single mothers and any others who offend their "sincerely held religious belief."
"Using my voice, I stand in solidarity with all my LGBT friends to repeal this extremely discriminatory bill," Adams added. "Hopefully Mississippi will right itself and I can come back and perform for all of my many fans. I look forward to that day. #stop1523"
The "Please Forgive Me" singer's declaration comes less than a week after Bruce Springsteen and the E Street Band canceled their Sunday show in Greensboro, North Carolina, because of the state's new law, which bars transgender people from using public restrooms in accordance with their gender identity.
"The law also attacks the rights of LGBT citizens to sue when their human rights are violated in the workplace," Springsteen said in a statement. "No other group of North Carolinians faces such a burden."
