How do I get my wifes email account (her iCloud) logged off of my iPhone 6?

[iMore Question]

I am showing logged into iTunes & App Store but not iCloud? This is causing her and I to recieve each other imessages/texts because she is logged into both iPhones with her email address. Please advise, thank you.

Settings > iCloud.

She's probably logged in there.
