What happens when the nation's most trusted therapist,

Oprah

, who has changed the lives of countless men and women -

and

given them free cars - has a life-changing experience herself?

What manner of Being could transform the tone, tenor and timbre, not to mention the pitch, roll and yaw, of Oprah's being-in-the-world so radically that it made her weep?

Barack Obama

.

"Just seeing [Obama] on stage, I cried my eyelashes off," The

Big O

told

Entertainment Tonight

about Obama's speech Thursday at the Democratic National Convention.

"It changed my life. I feel like I'm going to do better and work harder."

The transcendent beauty - and transcendental worth - of

Kate Moss

, 34, has been preserved in a life-size, solid-gold statue worth $18 mil.

"I thought the next thing to do would be to make a sculpture of the person who's the ideal beauty of the moment," said Brit artist

Marc Quinn

of using the model for the 110-pound statue, which goes on exhibit at the British Museum in London on Oct. 4.

NBC will premiere the second season of its little-watched, yet brilliant Zen-meets-

Polanski

cop show,

Life

, on Sept. 29. The smart, complicated drama stars

Damian Lewis

(

Band of Brothers

) as a cop who served 12 years in prison for a triple murder he didn't commit. Now he's back. But he's

not

angry: He practices Zen. Then again, he

is

totally out to get the dirty cops who set him up. And he eats a lot of fresh fruit. (Watch the first season with

Life: Season One

, due out on DVD Tuesday from Universal Studios.)

"I'll just have a little cake with my children and we'll probably watch some cartoons." So said

Michael Jackson

Thursday on ABC's

Good Morning America

about his plans to celebrate his 50th b'day, which was yesterday.

Think MJ's career is over? "I think the best is yet to come, in my true humble opinion," he said.

Though the classical world has been happy to welcome pop star

Rufus Wainwright

into its ranks, the opera he has been writing,

Prima Donna

, has hit a major snag: The Metropolitan Opera and Lincoln Center Theater this week canceled the commission. In a joint statement, the orgs say they "had not been able to come to a formal agreement with Mr. Wainwright and his management concerning plans for the work." Calls to Wainwright's reps weren't answered.

Opera e-zine Parterre Box (

) says the libretto, which Wainwright wrote in French, was a big problem since the Met is adamant that new operas be written in English.

Word has it that

Prima Donna

will find a new home at a festival in Manchester, England - circumstances for a less-pressured gestation.
