Spencer And His Two Favorite Blondes

We spotted Spencer Pratt, Heidi Montag and Spencer's other main blonde - his sister Stephanie - outside of Boulevard 3 last night. Word on the street is, Spencer threw his sis a birthday bash as MTV cameras rolled.

Stephanie is definitely a great addition to The Hills, and it looks like she might even be able to give Heidi some tips in the style department. Don't get me wrong - Heidi is a total hottie with a killer body, but the leather jacket isn't really working. I could also dedicate an entire blog to how wrong those baby blue gladiator heels are, but I won't.
