Jepsen announced her decision Tuesday in a series of tweets:
As an artist who believes in equality for all people, I will not be participating in the Boy Scouts of America Jamboree this summer. I always have and will continue to support the LGBT community on a global level and stay informed on the ever changing landscape in the ongoing battle for gay rights in this country and across the globe.

In his petition, Nance encouraged both Jepsen and pop band Train, also scheduled to perform, to denounce the BSA.
"As talented artists with incredibly loyal LGBT fans around the globe, I hope they will speak out quickly, and urge the Boy Scouts to end its dangerous anti-gay policy," he wrote.
Train announced Monday that they wouldn't perform unless the BSA changed their policy.
“When we booked this show for the Boy Scouts of America we were not aware of any policy barring openly gay people from participation within the organization,” the band said in a statement. “Train strongly opposes any kind of policy that questions the equality of any American citizen.”
The BSA, which has put off a decision on whether to overturn its ban on gay members, said the Jamboree would continue without Jepsen and Train.
"We appreciate everyone's right to express an opinion and remain focused on delivering a great Jamboree program for our Scouts," a BSA rep told NPR.
It's no surprise that Jepsen, who has supported gay rights in the past, pulled out of the event. The music video for "Call Me Maybe," resonated with gay viewers who were delighted by the video's surprise ending.
"When we shot the “Call Me Maybe” video, we weren’t even thinking the ending was not normal," Jepsen told Time last year. "I have so many gay friends that I love. It’s a regular thing. And if my video is encouraging that mind frame with other children and other people -- well, it’s about time, I guess!"
