Fame has made former Trump apprentice Omarosa Manigualt-Stallworth rather demanding:

Lady O gave an unlucky American Airlines agent the royal treatment when her coach ticket wasn't upgraded to first class on Sunday. Our witness reports, "It was the 8:15 flight from Las Vegas to Los Angeles, and there Omarosa was screaming at this poor woman, 'Don't you know who I am? I was on "The Apprentice!" ' "

The outburst failed to persuade the ticket agent, and the reviled reality-show castoff "had to slink back to coach where she fumed the whole flight," our spy said.

It seems her recent behavior may cause her to lose a Herbal Essence shampoo campaign.

A month ago, it was rumored that she had her eye set toward a Congress run. Will these episodes affect her plans for public office? Perhaps not...

It might be that she is simply a Sheila Jackson Lee fan.
