VIDEO: K-Stew on Miley Cyrus — " 'The Climb' is My Theme Song"

To get into the Bella's mindset in Twilight Saga: New Moon, Kristen Stewart says she created a moody playlist. But in Twilight Saga: Eclipse she didn't need it — she just used Miley Cyrus instead!

"I always listen to music, but I had particular music that I listened to on New Moon, but didn't really have to for Eclipse," she told MTV News over the weekend. "I just listened to my normal music. Bella's less tortured. She's less conflicted. I mean ... it's the most she's conflicted about the love triangle but that happens sort of at the end."

"The main conflict is the danger and the fact that she's losing her human life. That her family's gonna soon maybe go away," Kristen explained. "When I was doing New Moon, I needed the music and I needed my iPod all the time and I needed to be in my own little head, but in Eclipse ... the story was just different."

So now Kristen's just listening to what she likes best — Miley and Lady Gaga!

"I've probably been listening to a little bit of both," Kristen confessed. "But I don't know, 'The Climb' is my theme song — and I'm sticking to it."
