The Hill’s reality starlets, Miss Lauren Conrad and Lo Bosworth are officially moving out of the Hollywood Hills pad.

The two sister-like friends, are saying farewell to their house, and saying a big hello toa high-rise complex in the Westwood area of Los Angeles. A  close source says the reason for behind the move was, “She wanted more security, and being in a building with a doorman will allow her that.”

Recently, Conrad and her friends,  inlcuding Brody Jenner, with girlfriend Jayde Nicole, and Stephanie Pratt,  were at her home celebrating and having a barbecue, which of course all the MTV crew was filming. Speculation has it  that it was Conrad’s going away party.
