Finally, proof that the love between Justin Timberlake and Jessica Biel just isn’t that hot. Sexyback and Sexybutt kept their winter wardrobes on while scoping out the Paris 68 show at NYC fashion week yesterday. Timberlake spent the night promoting his William Rast line before spending some quality PDA time with Biel. “He opened the curtain and stepped Jessica behind it, then wrapped them in it before giving her a long kiss,” a witness after the afterparty told Page Six. “He ended up giving her a lap dance. It was pretty raunchy.” Just as long as there wasn’t a box over his crotch.
