Miley Cyrus is Sirius-ly Smiley

Miley Cyrus stops for a few fans and flashes a big smile on her way to tape The Howard Stern Show at the SIRIUS Satellite Studios in New York City on Thursday morning.

The 15-year-old pop star was in Nashville yesterday for the 2008 CMA Awards. Miley appeared on Live with Regis and Kelly this morning and when her birthday was mentioned – in just ten more days – here’s what she had to say: “The only problem with having your party at Disneyland and shutting it down is that you can never top it. So I’m going to spend my life trying to top my sweet 16.”

Miley will be on The Tonight Show with Jay Leno tomorrow, November 14th discussing her new animated flick, Bolt (out next Friday, November 21).

Can you believe there were 7,000 people at Miley‘s birthday party?! Watch the full interview below:
