Do I need bottles if I plan to breastfeed?

Hi all - I'm a FTM so this might be a silly question.  I am planning/hoping to exclusively breastfeed my baby once she is born in May.  I say planning/hoping because I know things can always come up that make this difficult.  However, if I am planning to exclusively breastfeed, do I need to buy bottles now too? Are they necessary or not?  Thanks for any feedback!
