Singer Colbie Caillat spills deets on upcoming album

Colbie Caillat is getting ready to make new music.

The singer - who collaborated with Gavin DeGraw on the tune "We Both Know" for the new flick "Safe Haven" - is hard at work on her next album.

"I want it to have a classic rock vibe to it - some hippie-ness to it," the 27-year-old told us before the Badgley Mischka fashion show Tuesday.

The "Bubbly" singer said she has written about 30 songs so far and will start recording this summer with a fall 2013 album release date in mind.
