Blonde Baby Sisters Ashlee Simpson & Nicky Hilton Hang in Hollywood (PHOTOS)

Battle of the Hot Ashleys!
Four hot ladies, one hot name!
These two left their famous families at home for a girls’ night out! Ashlee Simpson, 27, and Nicky Hilton, 28, were dressed to the nine’s as they held onto each other while walking out of the Sunset Marquis Hotel following a jewelry unveiling for Lia Sophia in West Hollywood Tuesday night. Paris Hilton and Kyle Richards were also in attendance.

Ash and Nicky reportedly headed over to dinner at celebrity hotspot Chateau Marmont following the party. 

The girls were ready for summer in their teeny, style-savvy ensembles. Nicky was dressed in a pair of army green shorts and black blouse, while the pixie-haired Ashlee wore a leopard print getup.

What else do these two have in common besides having famous older sisters and blonde hair?!? They were born two days apart! Nicky’s birthday is Oct. 5th, while Ashlee turns 28 on Oct. 3rd. Who’s your favorite sister duo: Ashlee and Jessica Simpson, or Nicky and Paris Hilton? Sound off in the comments!

Prior to girls’ night, we spotted Ashlee leaving a lawyer’s office with her big sis in May, perhaps going over her divorce filings from Pete Wentz? Check out the pics of the sisters below!
