Jason Allen Alexander isn't happy with his ex-wife, Britney Spears.

"(He) feels like Britney left him to figure all this out on his own, and he is upset with her," a friend told US magazine.

Her manager, Larry Rudolph, on hearing of the quickie middle-of-the-night nuptials, supposedly wired her: "Congratulations, you just gave away half your money."

Despite rumors that the pop princess gave her ex-hubby a Porsche and some cash in exchange for an uncontested annulment, Alexander's hometown friend Jared Prescott said, "He hasn't gotten paid for anything, I'm still paying for all his lunches."

Meanwhile, Spears has been keeping a low profile since the annulment.

"We've been having fun not telling people where she is," her spokeswoman said earlier this week.

"The magazine shoot that didn't happen last week is being rescheduled, and then she's off to Europe to play a few dates there."
