Lindsay Lohan wants permission to have a very special visitor in rehab -- her longtime drug dealer!

Linds, who's partway through a 90-day stint at the Betty Ford Center, needs to provide a list of names of those planning to drop in, and she decided she needed to see the unnamed man -- but her request was denied.

A source close to the situation tells Radar Online, “Lindsay advised Betty Ford that she wanted to invite a male friend, whom it’s known she partied with for years and had provided drugs to her, including cocaine. She was already livid that the doctors have taken away her Adderall. She thinks they are just out to get her and make an example out of her, because she is a celebrity. She hates being there and is counting the days until she will be released.”

Richie Sambora has broken his silence -- ever so slightly -- over why he left the Bon Jovi tour.

When Sambora left the tour earlier this year, there was speculation that he'd fallen out with Jon Bon Jovi over money, and that was followed by reports that he was back in rehab. Jon added some fuel to the alcoholism fire recently when he said, "It’s getting more and more difficult every day to not just sit here and say something… Because all I can say is this -- it’s for personal reasons. He's been through it before."

But Sambora has fired back and says he has not fallen off the wagon. "I don't have any major problems in life right now, I love my fans, and I feel bad for them at the moment... My opinion is Jon wants to see if he can pull off stadiums by himself. He is making it very difficult for me to come back... Jon needs to stop talking about me publicly. I am fine working very hard on my fashion company, Nikki Rich, and this is a private matter."

Bon Jovi, minus Sambora, start a U.K. tour next month.
