Jon Gosselin is channeling his inner Biz Markie -- claiming the girls he was kickin' it with on Memorial Day weekend (sans Kate) are nothing more than friends.
Jon told People.com, "The two women with whom I've been photographed are family friends – Lauren Glassman and Lauren's daughter, Hailey.
"Lauren's husband, Dr. Larry Glassman, performed Kate's tummy tuck surgery, and since the surgery we've become friendly with the Glassmans."
Jon was out again with the twosome at the Riverside Square Mall in New Jersey this weekend -- where he went on a $2,000 on a mid-day shopping spree.
So where was Kate while Jon was playin' around with his lady friends? She was in North Carolina, showin' off Glassman's work.
