Aaron Carter Breaks Engagement, Singer Proposed To Former Playboy Playmate A Week Ago

Pop singer Aaron Carter has broken off his engagement to his older brother’s ex.

The 18-year-old called off his engagement to 22-year-old actress Kari Ann Peniche just a week after he proposed onstage in Las Vegas, Us Weekly reported on its Web site Sunday.

Peniche is an ex-girlfriend of Carter’s older brother, Backstreet Boys singer Nick Carter. She’s also a former Miss Teen USA and former Playboy playmate.
