Los Angeles, May 27 - Socialite Kim Kardashian's engagement to basketball player Kris Humphries has reportedly upset her ex-boyfriend Reggie Bush.
According to Life and Style magazine, Bush was 'pretty cut up' by the engagement news and backed out of the launch party for the event.
An eyewitness claimed to have overheard Bush's friend Cody Green as saying: 'We heard Kim got engaged, so we think that's why - didn't turn up. He must be pretty cut up. He sounded like he was, and that was why he didn't make it down,' reports aceshowbiz.com.
Bush and Kardashian began dating in 2007. After several years of dating on and off, the two decided to end their romance last March.
