In her latest YouTube video, Miley Cyrus and best friend Mandy Jiroux urged fans to go green; i.e. save the environment.

Now, the Disney star is asking fans to fork over green; i.e. pay $250 to attend her 16th birthday party at Disneyland.

According to Entertainment Tonight, Cyrus — who took in $18.2 million last year — is selling a limited number of tickets to her Sweet 16 celebration. They go on sale August 30 at 9 a.m. PDT.

"It's gonna be an awesome party with more than 7 things I like," she told the entertainment news show.

"It's gonna be totally awesome. I hope it's a great time."

Is there some catch here we're missing? Or is Miley Cyrus really asking fans to pay their hard-earned money just for the chance to be in the same vicinity as her?

If you believe the latest Miley reports, she's apparently in the Us Weekly-described "early stages" of dating Adam Sevani.

Yes, that's the same Adam who is one-half of ACDC—the dance duo that's also comprised of Step Up 2 director John M. Chu and that had a long-running YouTube dance-off with Miley and her BFF Mandy Jiroux, aka M&M Cru.

But Miley, 15, and 16-year-old Adam "are just friends," a rep for the Hannah Montana star tells me. Adam's rep did not comment. Still, could there be anything to the romance rumor? A friend of Miley says, "She's only 15, so who knows what will be next week or even tomorrow."
