The 23-year-old singer "didn't care" about scrutiny around her personal life until her breakup with the 21-year-old heartthrob. "To me it was: I'm 18, I have a boyfriend, we look cute together, we like that. Then I got my heart broken and I cared," she revealed. "Because people had no idea what was going on, but everywhere it was a million different things I was kind of in a corner, banging my head against the wall. I didn't know where to go."
Fans of Gomez and Bieber shouldn't expect a rekindled romance anytime soon. Gomez said that their on-again, off-again relationship has made her "so exhausted."
"I honestly am so done," she added. "I care about his health and well-being. But I can't do it anymore."
Gomez also cleared up any rumors that she has beef with Miley Cyrus. "Obviously, she wouldn't want to be doing what I'm doing, and I wouldn't want to be doing what she's doing. But I'm a fan of her music -- I don't know if she'd say that about me," Gomez -- who dated Nick Jonas after Cyrus -- explained. "We never feuded. We both liked the same guy when we were 16. It was just a Hilary Duff–Lindsay Lohan thing: 'Oh, my God, we like the same boy!' We are now completely settled in our own lives."
While Gomez has yet to confirm any new romances, it does appear she's moved on from both Bieber and Jonas. ET got exclusive pics of the "Good For You" singer holding hands with model Samuel Krost on one of their many outings.
