TV shrink Dr. Phil McGraw canceled his Britney Spears intervention show Monday amid criticism that he violated her privacy by visiting her in the hospital.

In a statement on his Web site, Dr. Phil says, "As was widely reported this weekend, at the request of concerned family members, I visited Britney Spears in the hospital. The details of that visit will, of course, remain private. We had planned to tape a Dr. Phil Now show today, focusing not on the tabloid side of Britney's latest problems, but instead on the very serious issues surrounding this case."

The statement goes on, "Clearly, it is not just Britney's family struggling to find a way to protect adult children who cannot be ordered or compelled to seek help. Because the Spears situation is too intense at this time, and out of consideration to the family, I have made the decision not to move forward with the taping at this particular time. Britney and her family are in our prayers, and we ask that they be in yours."

Earlier, sources told TMZ.com that Britney's father, Jamie Spears, wanted nothing to do with McGraw's intervention show about the singer.

McGraw defended himself Monday against criticism that he violated Spears' privacy when he visited her in the hospital Saturday morning.

"I want to set the record straight. I went to see Britney at the request of her family. I talked to Lynne, Jamie and Brian, because they were frustrated that she wasn't going to be held for a longer time," McGraw said on CBS' "Early Show."

Asked how he had come to be involved in the saga, Dr. Phil said, "Thursday night, the phone rang, it was Lynne, clearly she was very upset. Any parent would be. I was first contacted by her family a year ago and had maintained a running dialogue for the last year or so."

TMZ.com says it spoke with eight psychiatrists who don't think Dr. Phil should have been allowed in to see Spears when he doesn't have in-patient privileges.

"Britney didn't ask for it, Britney didn't know about it" and Spears walked out when Dr. Phil walked in, said TMZ.com managing editor Harvey Levin.

Sources also told FOXNews.com that Spears angrily kicked McGraw out of her room and demanded he leave at once.

Dr. Phil said he eventually did meet with Spears for about an hour. He told "Entertainment Tonight" and "The Insider" in a press release that she's in "dire need" of medical and psychological help despite being let out of the hospital.

"My meeting with Britney and some family members this morning in her room at Cedars leaves me convinced more than ever that she is in dire need of both medical and psychological intervention," McGraw told the programs.

"She was released moments before my arrival and was packing when I entered the room," he said. "We visited for about an hour before I walked with her to her car. I am very concerned for her."

Meanwhile, the "responsible" people in Spears' life are trying to convince her to voluntarily enter a mental hospital, sources told TMZ.com.

Spears' loved ones believe she'll never regain custody of her children unless she undergoes intensive, in-patient treatment for what appears to be a severe bipolar disorder, but Britney does not want to enter a hospital, TMZ reported.

Another report says Spears didn't test positive for drugs or alcohol during her two-night stay at Cedars-Sinai.

A "reliable source" told People magazine that Brit "tested clean ... This lady is as clean as clean can be, and has been for some time."

Spears was hospitalized under mysterious circumstances Thursday evening following a standoff with police in which she allegedly refused to hand over her two baby boys to ex-husband Kevin Federline.

On Friday, a court commissioner gave Federline full custody of the two children and suspended Spears’ visitation rights following the incident.
