The former Destiny's Child singer always gets mobbed by fans when she attends religious services, so has made the difficult decision not to go anymore.
She said: "I can't really go to church anymore, which is a shame. People have come up to me in church during the sermon and, of course, people watch everything I do. They come up and take pictures on their mobile phones too.
"They are very nice, but I think God understands if I miss Sunday service!"
Beyonce also revealed she will never officially confirm that she has married rapper Jay-Z.
She added to Britain's Look magazine: "I don't deny it. I just don't talk about it. We have never talked about us and it has kind of protected our relationship.
"A lot of actresses that have had successful relationships don't talk about them, so neither do I. I just want to protect my private life."
