People.com Celebrity Aaron Carter's Vegas Engagement The singer pops the question, his Playmate girlfriend tells PEOPLE By Mark Gray Published on September 18, 2006 06:55 PM Share Tweet Pin Email Singer Aaron Carter is engaged to Playboy model Kari Ann Peniche, the bride-to-be confirms to PEOPLE. “I’m very excited about it,” Peniche tells PEOPLE. “Aaron is the most genuine person I know. He’s kind, loving, and I love him so much.” Carter, 18, popped the question to Peniche (who previously dated Aaron’s brother Nick) on Saturday in Las Vegas while they were onstage in front of 200 people during the Playboy Comedy Tour at the Palms Casino Resort. “I don’t remember it happening. It was such a blur,” says Peniche about the surprise proposal. “I had no idea he was going to do this, but I’m glad he did.” The couple, who plan to wed in the next six months, hugged and kissed after Peniche accepted the proposal, Playboy tour producer and comedian Cort McCown tells PEOPLE. “He said he was going to do it, but we thought he was kidding,” said McCown. “He was really nervous.” Peniche, 22, was named Miss United States Teen 2003, but was stripped of her title after posing for Playboy. Carter is set to appear on an E! reality show about his family, House of Carters, premiering next month.
