She was on the Sharon Osbourne show on Halloween and Ozzy and Sharon were drooling all over her. Sharon kept telling Shannen what nice tits she had and how great she looked in Playboy. It was funny
Shannen is hosting a show called Scare Tactics and that show ROCKS! It's so funny because they scare the bloody hell (as Sharon put it) out of people. They are probably paying her fairly well for the show, so I don't think she was hurting for money. She probably did it for publicity more than money.
