Jesse McCartney: San Diego Stud

A t-shirt clad Jesse McCartney and his girlfriend Jasmine Waltz arrive at their hotel together in San Diego on Saturday afternoon (July 25).

The 22-year-old musician was seen out with former Lost actress Maggie Grace later that night. The duo were seen at the 2009 San Diego Comic Con earlier in the day.

Jesse tweeted, saying, “Driving to San Diego for the day! Comic Con is going on right now. This traffic is driving me nuts though!!”
