Miley Cyrus is allegedly ruining her parent’s marriages. Sources say the 16-year-old takes up most of father Billy Ray Cyrus’ time as they constantly travel together and film Hannah Montana shows.

Cyrus’ mother Tish and younger siblings are allegedly tired of the singer stealing all of the attention. “Tish is tired of Billy Ray not being at home. All summer, while the kids were out of school, Billy Ray wasn’t around. It was supposed to be family time, but Billy Ray was too busy with Miley,” reveals an insider. “The kids missed him, too. They complain, ‘It’s Miley, Miley, Miley, all the time. What about us?’ They feel like they don’t even exist in their father and sister’s world.

Meanwhile, Cyrus is rumored to have dumped Jonas Brother singer Nick Jonas in favor of a relationship with her Last Song co-star Liam Hemsworth.
