Pat O’Brien was fired from The Insider again for more erratic behavior just last week. Now we hear Pat has checked into rehab again. On the bright side, rehab is better than dead.

Crazy Pat O’Brien has finally reach the end of his rope. CBS has decided to let him go. The trouble started when O’Brien sent a message to the staffs at Insider and Entertainment Tonight over the past weekend that read:

"Hi, folks, I just spent a couple of days in Iowa – I’m a little bit of a favorite son there – and I spoke with maybe a thousand people and was very hands-on. Even Joe Biden said, ’You should be running (for president)!’ But what I came away with was, these people can’t afford gas, books, food or schools or movies!

"I was approached a hundred times by people asking, ’Can you help us?’ I tried to tell them we care, but they didn’t buy it. They wanted to, but watching Anya and Lara Spencer pick out accessories makes the viewers want to vomit. I’ll get killed for this, but I’m actually the one not afraid for my job. I want people to be happy."

The segment on "The Insider" O’Brien referred to is the Look for Less feature, in which Spencer and her stylist show viewers how to look like her affordably. "It’s a very popular segment and gets the most hits on the Web site," a source said, adding:

"He is very jealous of Lara Spencer, because she is the sole host of the show – she has his old job. It’s amazing the show sent him to interview Joe Biden. It’s just so arrogant and comes from his insecurity and jealousy."

CBS realized O’Brien’s ego had grown too big, so they decided to let him go like a ballon filled with hot air. CBS released this statement:

"Pat O’Brien is a talented broadcaster who has been a part of The Insider family from the very beginning. Although we have decided to part ways, everyone at CBS Television Distribution and The Insider greatly appreciate and respect all his contributions to our show. We wish Pat much success in his future endeavors."

Pat might think about getting a psychiatric evaluation, and treatment for his apparent pathological narccissm.

Pat O’Brien (60) and his girlfriend Betsy Stephens have been together five years, and they’re getting married next fall, maybe. O’Brien said:

"It’s probably going to be next fall. We’re in love and in no big hurry. We don’t know if it will take place, in Jamaica, New York, or Nantucket."

Stephens, who has two young daughters and whose company, B for Betsy, specializes in handmade accessories and apparel, said:

"I think we’re going to sneak off and do something really romantic. He’s a smart, interesting man, poetic. He’s wonderful."

Poetic … romantic? Listen to the voicemail messages O’Brien left another woman back in 2005. At the time O’Brien was on cocaine, and had been with Betsy about 2 years already. She’s in it for the money.

Cojo and Pat O’Brien were thinking as they uncomfortably prepared for The Insider broadcast ______________

After finishing his second try at rehab, Pat O’Brien (60) is scheduled to return to Insider on April 14th. Good luck Pat. Stay sober.
