How do you become a famous singer if you don't know how to play many instrument's?

No one says you have to know how to play many instruments..i suggest joining a band that plays your kind of music,and you be the singer of the group.If you do that u needa be a good singer first,otherwise you will not get anywere with singing.Maybe you can learn how to play other instruments..Maybe something you see most singers using like a piano,guitar,or even drums.Im sure there are even more instruments to play(for ex:the fiddle).Oh i forgot you will have to even have to practice hard and have alot of concerts or something.
