After sending the Easy A actress an apology on the social networking site, the iconic singer sat down with E! News to talk about why she called off the mini-feud.
"I never understood the thing about not saying you're sorry because it's so easy…it doesn't take any time and it just dissolves all the bad feelings," Cher told Alicia Quarles. "It just lets it go, and we can't hold on to that kind of stuff. It makes you sick."
The Twitter showdown between Bynes and Cher went down after a fan asked the entertainer if she was upset that Bynes called her "ugly and a flop," to which Cher replied, "Who's that?"
After Bynes tweeted, "This is my twitter. I say whatever I want. Thanks!," Cher sent over an apology, saying, "you got That One Right! Sorry about shade, Sweet-Heart, it was unintentional...Promise."
Cher said it's her preference to serve as a mentor for younger people on Twitter, rather than argue with them.
"It's a rough time in history for kids," Cher told E! News. "Sex didn't kill you when I was young and people weren't trying to blow up buildings."
"I feel a lot of compassion for these young kids that are growing up that don't really understand exactly what's going on. It's really rough. That's why I do a lot of tweeting…I feel kind of like a mother. It's something that gives them a little insight into things and it doesn't make them think that all grownups are the enemy."
