George Clooney? Not coming, says a Capitol Hill newspaper.

The Boss? Still a chance he’ll show, reports ABC News.

And Oprah?

No confirmation, but there’s talk – especially among chauffeurs in Charlotte.

One limo-riding source told us about a conversation on the way to CLT-Douglas Airport.

“Oh yeah,” her man behind the wheel said, “certain drivers are being interviewed to transport a VIP around town.”

“You mean Obama?” our source asked.

“No, the other VIP,” said her driver. He called this special someone “a media mogul woman” and said the guessing in his circles pointed to Oprah.

So will Miss Winfrey be riding around town convention week in some dark-windowed luxury sedan?

We got no confirmation from CLT’s Rose Chauffeured Transportation or from Blue Diamond, a Raleigh company that’s opened temp offices here just for the DNC.

But we did uncover one thing: With so many rich & powerful folks headed this way, biz is boffo for luxury transportation companies here.

“We’ve been sold out for a month,” said Rose operations manager Tom Holden. Rose even brought in eight other companies outside CLT “to help us cover the needs.”

One is Blue Diamond, whose sedans and SUVs will cart around VIPs from some of the big TV networks.

“You basically reserve that particular vehicle for that client for a 12-hour day,” said Blue Diamond CEO Carrie Peele.

Cost per day: $1,200-$1,500 – peanuts for Oprah.

You can’t go to this

In our spare time, we like to page through the lists of late-night parties skedded for convention week.

On Sept. 2: the “You Can’t Get Into This Party” party at uptown’s Capital Grille. It’s for “Democratic insiders,” according to sponsors. “If you have not received your invitation, it means you’re not invited.”

We prefer this one on Sept. 4: the People for the American Way Foundation’s “Celebration of the Right to Vote.” Sounds serious, but, hey, it’s at ze Kazba in the EpiCentre.

And check out some of the fun-loving names on the host list: Alec Baldwin (“30 Rock”), Jane Lynch (“Glee”), David Hyde Pierce (“Frasier”), Kathleen Turner (“Body Heat”), and Seth McFarlane (“Family Guy”).
