The 29-year-old singer - who is known for her sexy dance routines - finds her sets often don`t go quite as planned due to her runny nose, leading to bubbles forming when she can`t blow it.
She said: "My nose runs a lot and when I`m singing I can`t blow it, so there have been occasions when I`ve ended up with a bubble coming out my nose."
Beyonce`s nose is not the only problem on stage - the `Girls (Who Run the World)` hitmaker confesses she needs to have wind machines blowing air around her constantly because she is a profuse sweater.
She added: "Everyone thinks I have fans because I`m being fashionable, but I work so hard on stage if I didn`t have them I`d be dripping."
In addition to sweating and excess mucus, Beyonce - who is married to hip hop star Jay-Z - also finds she no longer likes her feet due to the stress she has put on them from dancing in heels.
Speaking on a TV show set to air on ITV in the UK in December, she said: "If I could change one part it would be my feet. After all the years dancing they`re a little beat up. And I wear big earrings because I don`t like my ears."
However, her foot problems did not stop Beyonce spending £9,000 when she took a trip to London`s Oxford Street earlier this week.
A source who saw her shopping said: "It was like that shopping scene out of the film `Pretty Woman`.
`Everyone was gobsmacked by the speed she was choosing clothes. When she hit the shoe section she picked up even more speed. The woman clearly loves footwear."
