E-mail for my apps has changed

[Mr_AliMaMa]

I checked my apple id under settings and its not changed but whenever I go to App Store to update or install a new app a new email Id shows up instead love@love.com

I didn't pay attention to it and entered my password and it worked this time said there was something wrong. Is this some sort of error?
