Rimes, 28, and Brandi Glanville, 38, have made digs at each other on Twitter since 2009 when Eddie cheated on his wife with Rimes.
But LeAnn wrote yesterday: 'As a collective unit, Brandi and I would like all negativity to cease toward one another. We have communicated and have a direct understanding that we are only ourselves on Twitter and have no other accounts that try to destroy one another. Please for our families' sake stop the hate now and let us live our lives.
The singer added: 'We don't need opinions or outside help in order for that to happen.'
Brandi re-tweeted her post.
