Detroit Tiger All-Star pitcher Justin Verlander is rumored to be dating Sports Illustrated swimsuit model Kate Upton.

The two hit the Aerosmith concert and rode mechanical bulls at a bar last weekend in Detroit, adding to those rumors. The next night, Upton turned up at the Detroit Tigers game wearing an old school Detroit cap.

Justin has reportedly been in a long-time relationship with girlfriend from college. Kate Upton had been dating NY Jets quarterback Mark Sanchez.
