Odd...

From TMZ and is a reminder needed that dr. quack-phil isn't a real doctor? He has no business trying to "treat" britney.

TMZ has learned Dr. Phil's visit with Britney Spears was not exactly as advertised.

People on the 7th floor at Cedars-Sinai Medical Center say the doctor arrived about 7:30 AM Saturday. We're told Britney did not invite him in; she didn't even know he was coming. Sources say it was Brit's parents who told Dr. Phil to go to the hospital. When he walked into her room, we're told, a blindsided Britney walked out -- and eventually came back.

Sources say Phil tried speaking with Spears for about 15 minutes -- not an hour as Dr. Phil's press release states -- but she wanted none of it. We're told Phil was doing almost all the talking. As for walking with her to the car on her way out -- again, as his release states -- we're told if he was walking behind her, that's news to her. She absolutely was not accompanied by him.

Sources say Dr. Phil somehow convinced Brit's mom and dad to be on his show, which will tape Monday and air Tuesday (it was just moved up a day), but as one person put it, "Based on the interaction between Dr. Phil and Britney this morning, it'll be a cold day in hell before Britney goes on his show." We're told she absolutely will not appear on the program.

Sources say Dr. Phil wants to do a television intervention, something that isn't sitting well with some of the people who have known for a while that Britney has a very serious mental condition -- likely a bipolar disorder that is now in the red zone.

TMZ contacted Cedars to find out why the hospital let a television doctor on a floor that has such fragile patients, particularly since Britney had no idea he was coming. It's especially troublesome that Cedars let Dr. Phil go uninvited to Britney's room, since she had already been discharged and presumably had a right to know if someone wanted to visit. A Cedars rep made it short and sweet, telling us, "No comment."

A rep from the "Dr. Phil" show had no comment as well, other than "Dr. Phil met with Ms. Spears at family members' invitation."
