DJ AM & Jessica Stam Swap Spit

Adam “DJ A.M.” Goldstein and Canadian supermodel girlfriend Jessica Stam go for a stroll in NYC’s SoHo on Tuesday afternoon with his thumb hanging from the belt loop of her shorts and his hand… cough.

The loved up couple were very affectionate and were spotted kissing in Washington Square Park.

CUTE COUPLE or TERRIBLE TWOSOME?

A.M., 34, and Jessica, who just turned 21 this week, have been dating for about a month now. The one time overweight DJ is the ex-boyfriend of Nicole Richie and Mandy Moore.
