Lauren Conrad's Instagram feed is filled with perfect photographs -- and the Laguna Beach and Hills starlet just shared a wonderfully mysterious image.

No other information is available at this time, but be sure to check Lauren's Twitter account on Tuesday, May 31 at 11amET/8amPT (an important date for one major reason) for exact details. Now, we wait and twiddle our thumbs (6 DAYS, FOLKS!).
