Washington, May 29 : Beyonce Knowles says her feet ‘throb’ when she goes to bed after performing, courtesy her spiked stilettos.

The singer admits she’s putting her feet through hell on her 110-city world tour because she refuses to take to the stage without her trademark designer high heels.

"When I come home and take them (shoes) off, I''m like, ''Oh my God! I wish I could just chop my feet off!'' But while I''m dancing, I''m thinking of the choreography,” the Daily Express quoted her as telling Self magazine.

"I don''t think about my feet until I''m trying to go to sleep and they''re throbbing," she added. (ANI)
