On Monday night, Cyrus performed her new breakup song "Slide Away" during the show, with Carter joining her backstage and at an after-party for the event. After being spotted kissing in Italy the day after Miley's split was announced, the two have also been seen in L.A. together.
Last night, Cyrus skipped the red carpet, but did bring Carter with her for her performance — Carter was seen backstage with Cyrus, affectionately caressing her head, and, according to ET, putting her hand on Cyrus's butt. "They looked very much like a couple," a source told ET.
"Kaitlynn was swaying at the side of the stage as Miley rehearsed 'Slide Away,'" the eyewitness said of their interactions earlier in the day, during rehearsal. "Afterward, the two walked backstage, hugging each other."
The two were also spotted holding hands on their way to an after-party.
“I can admit to a lot of things but I refuse to admit that my marriage ended because of cheating," she wrote. "Liam and I have been together for a decade. I’ve said it before & it remains true, I love Liam and always will.”
