Lauren Conrad has a new book, 'Infamous' out this week, but more importantly, the reality star, author, and fashion designer has a new hairstyle as well.

LC followed Michelle Obama's lead and has recently been spotted rocking bangs. But when she stopped by the Barnes & Noble at The Grove in Los Angeles for a book signing on Tuesday, Lauren's new 'do was swept up and carefully hidden by a ballerina bun.

Though we love the new bangs, you can never go wrong with a classic ballerina bun up top, especially when you need a clean, non-fussy look for a more formal event. And besides, it's Lauren Conrad - we'd love her in just about any hairstyle.
