As vague as this sounds, Montag has been pretty clear that she faced too much drama with Conrad and she had to let her go. Some fans may remember that Montag posted another suspicious tweet that could've easily been referring to her former pal.

Conrad previously opened up to Cosmopolitan about how despite the chaos she faced when she and Montag were friends, she's focusing on other things in her life now.

"I'm not really involved in that anymore," she said via E! News. "I don't think it has anything to do with me. You just have to focus on the good people in your life. Focusing on what you lose is only going to make you sad."

The star then explained how being on reality TV made her stronger.

"Scandal was always around me," she said. "And I think one of the best things [about that] for me is that your life becomes more big-picture. You have to develop a thick skin really quickly. It toughened me up, which is good."
