Miley Cyrus and Kaitlynn Carter took a wrecking ball to their romance after just a month of dating, a new report claims.

A source told People that Cyrus, 26, "doesn't want a serious relationship."

The insider added, “She and Kaitlynn spent every day together and it just [wasn't] anything that Miley wanted to continue doing. She wants to focus on her career.”
