There is no secret that some of the most famous men magazines (Playboy and Hustler) want to sign with Denise Milani for some pictorials. However, until now she turned their offers as she doesn't want to post naked. Actually, she became so famous part because she keeps declining on these magazines. A contract with Playboy for example may be something tempting but not for Denise.
She can realize that her appearance on Playboy covers can be tricky for career. Denise is the "Queen of eroticism" but only because she never posted naked. She is beautiful, a beautiful body and a cute face.
Her non-nude pictorials are amazing and extremely popular so why would she change that? She is successful already and all she needs now is bigger contracts. The main think that Playboy can offer is publicity. If an unknown celebrity appears on Playboy covers, she suddenly becomes popular. A famous celebrity will post for Playboy only if her fame is about to fade and she needs a new boost for career. Denise doesn't need more publicity and she doesn’t need a career boost.
For now, she will decline every offer from such a magazine. However, time will pass and we can't know what is going to happen next year or over 5 years from now.
