Lauren Conrad is taking over InStyle.com on July 29, and we couldn’t be more excited! Following in the footsteps of our previous guest editors Elizabeth Banks and Kate Hudson, Conrad will dish out exclusive content—from beauty tips and styling advice to so much more—on our site throughout the day. But that’s not all: The blogger and style star will hold an exclusive Twitter chat with InStyle.com that same day at 4 p.m. EST, when you can tweet her all your burning questions using #AskLaurenC.

Make sure to come back on Tuesday, July 29, as we roll out all of Conrad’s special content. In the meantime, click through some of her best looks ever in our gallery.
