It's official. 'Hannah Montana' will end after four seasons. Miley Cyrus and company will start shooting new episodes on January 18th and the finale episode will probably air towards the end of the summer.

It's definitely time for Miley to hang up her Hannah wig. But could her little sister be looking to step into the role? Miley's lil sister is growing up fast! In fact, today is Noah Cyrus' tenth birthday -- that's just two years younger than Miley was when she auditioned for the role of Hannah.

Even though she's just hitting the double digits, the mini superstar's already been on TV, in a music video, and featured in a major movie. But then again, Noah is the youngest sibling in a famous family, so it's no surprise that she's following in Miley's footsteps.

Are you sad 'Hannah Montana' is ending? How do you want to show to wrap up? Let us know in the comments. And happy birthday, Noie!!

The Jonas Brothers took a break from their super busy tour schedule to make an appearance in Hollywood yesterday to support their little brother Frankie Jonas (also known as 'The Bonas Jonas').

Frankie was there to premiere the new Disney movie Ponyo, which hits theaters August 14th.

In the animated movie, Frankie plays Sosuke and Noie Cyrus (yup, that's Miley Cyrus' little sister!) plays Ponyo.

The film is based on the story of The Little Mermaid. Have you heard about this movie? Will you go and see it?
