Now that fall is almost here, the second-half-of-summer fling is apparently over: Miley Cyrus and Kaitlynn Carter have apparently called their brief rebound relationship quits, with a source telling People that while "Miley and Kaitlyn broke up," "they're still friends." That news follows roughly six weeks after Cyrus split from her husband of seven months, Liam Hemsworth; Cyrus' breakup came a week after Carter separated from husband Brody Jenner. Cyrus and Carter have "been friends forever and were there for each other when they were both getting separated," the source says, "but they’re just not in a romantic relationship anymore."
