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, The Daily Telegraph reported.
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."
