Kevin Mazur/WireImage.com We can totally imagine what happened here. Katie Holmes and Tom Cruise were headed out to Miami's Mokai nightclub in their sports jerseys and sweats, when they were stopped by their good friends Jennifer Lopez and Marc Anthony, who offered to lend them some hipper threads. Kate got a scarf from Jenny's El Cantante phase, and Tom borrowed a gold jacket from Marc's cameo in Carlito's Way. Hey, that's what friends are for.
