The Hills are alive with sexual harassment charges today, and the accuser, Heidi Montag, is planning a lawsuit against Hills creator Adam DiVello, who allegedly put "one hand directly on her butt cheek" during a photo shoot in March. The harassment allegedly continued on set with the executive producer asking Heidi to "strip down to a bikini for scenes," and according to one insider, DiVello "wasn't on set much for six seasons until Heidi got her new boobs." An MTV spokesperson has denied the charges, while Lauren Conrad and Lo Bosworth have also come to DiVello's defense. [Daily News]
