Adele will never do a huge global tour because of fears that she could lose her voice.
Doctors have warned the pregnant singer that her vocal cords could fail due to her gruelling workload.
Last year she lost her ability to sing after a polyp was found on her vocal cords.
The polyp was surgically removed.
"It is basically a clean slate in my throat. It doesn't mean it won't happen again. If I decided to go on a 200-date tour, it will happen again through exhaustion," Adele had said.
Her admission could be bad news for fans who long to see her in concert.
