The pair, who play Summer Bay's Romeo Smith and Ruby Buckton, started dating earlier this year after falling for each other on the soap set.
Speaking to TV Week, Mitchell confessed that he often bickers with his girlfriend but believes the rows are a good thing.
He commented: "We fall out about anything and everything. We like to have arguments - playful ones. I think that is the basis of our relationship. If you agreed on everything, it would be a bit boring, wouldn't it?"
Offering her own take on the disputes, Breeds said: "We've never had an actual fight, but we do have little tiffs. I push his buttons. We're not perfect - we're just a healthy, normal couple."
Mitchell recently said that he would not like Breeds to be his love interest in Home and Away.
