Teen pop star Aaron Carter is in love again - just four months after calling off his nine day engagement to Playboy model Kari Ann Peniche.

Carter, 19, hit the headlines in September when he proposed to Peniche on stage in Las Vegas after only a few weeks of dating. However, the Crazy Little Party Girl hitmaker soon realised he was too young to get married and called off their engagement.

Carter now claims he's in love with singer Kaci Brown, 18, after just seven days.

He says, "Now I'm in a great relationship. I've only known her for, like, seven days, but I have a connection with her that's like nothing else I've ever experienced."

"It's really amazing."

Brown adds, "He's just one of the sweetest most genuine people I've ever met. He's so talented and it's inspiring."
