According to sources, Kardashian and Bush had lunch together at the Beverly Hills Hotel this past weekend and were spotted laughing and smiling. While fans reportedly asked the couple for autographs and wanted their pictures taken with them, both the reality TV star and Bush "played it cool."
Kardashian and Bush broke up in 2010 after dating on and off for several years.
Kardashian eventually moved on to Kris Humphries and the couple got engaged in May after six months of dating. They wed in late August, but Kardashian filed for divorce in late October after being married to the New Jersey Nets star for only 72 days. The couple is now in the process of finalizing their split.
