Miley Cyrus: Bobby Coleman Will Do Anything For Five Bucks

Miley Cyrus shows off her pearly whites as she sits down to talk with Robin Roberts on Good Morning America on Monday morning (March 22).

The 17-year-old actress, in a Isabel Marant silk blouse, opened up about her new role as Ronnie in The Last Song and about working with the cast, including new boyfriend Liam Hemsworth. Check it:

On Bobby Coleman: “”He is probably one of the most hysterical kids I’ve met in my life. This kid will do anything for five bucks. By the end he literally had a receipt for me. It was like $80. I paid him 10 bucks to go ask Liam if he liked me. I sent him back and forth. It was really funny.”

On Greg Kinnear: “”He is very laid-back, but he’s really funny. Mostly, he plays deeper darker roles, and he’s so hilarious. … So many times I felt like I was back on the [Hannah Montana] set with my dad.”

On leaving her Hannah Montana persona behind: “It’s bittersweet. It’s been kind of hard. It’s like, ‘Oh my gosh, I don’t have this to fall back on.’ We’ve been doing this for five years, then we start to think this is our life, and to leave this behind is hard. [But we're] excited to go on to new chapters in our life. It’s given me such a great start.”

On Liam: “It was really good [working with Liam], because it makes you want to come to work and … look good. I’m trying to make people see my work as a real actress and more mature. And when you have someone who loves you and wants you to do well, you really want to help each other, and you want to make each other look good. We both were trying to get our point across [that] we can do more than [what people know us as].”
