Taking advantage of the hot night life scene, Paris Hilton and Jessica Simpson both ended up partying at Bar Deluxe in Hollywood last night (January 8).

The “Simple Life” hottie arrived looking ready to party in a super sexy black minidress, accompanied by her sister Nicky as the two pried past lined up paparazzi.

Meanwhile, the “Come on Over” songstress got plenty of paparazzi attention as she meandered through the crowd, looking a bit bewildered at times.

Miss Simpson was joined by her sister Ashlee for a bit, but the new mommy headed home early after only a brief stay.
