Jessica Simpson has reportedly spoken out on the Nick Lachey, Vanessa Minnillo sex pic scandal-and the buxom blonde isn’t impressed.

“Jess was lunching with some friends and someone brought up the hot tub pictures. Jessica scrunched up her nose, made a face and said, ‘That is sooo tacky. Have some modesty!” a mole dishes to the tabs.

“Jessica thinks that carrying on like that was classless. She suspects Vanessa knew she was being photographed and played to the cameras. She wouldn’t put it past her to have staged the scene.”

“If I had a body like Vanessa’s, I’d show it off, too,” a friend at Jess’ table remakred. Believe it of not,” the source continues, “Jess still compares herself to Nick’s current girlfriend. She even asks her friends, ‘Is she prettier than me?’”
