Kim Kardashian caught up with an old friend last weekend: her ex-boyfriend, football player Reggie Bush. According to TMZ.com, they met up for lunch at a Beverly Hills hotel. Sources tell the website the ex-couple has been spending a lot of time together lately, but it's unclear if they're romantically involved again.
