Heidi Montag Celebrates With Voom

As reported last week, The Hill's Heidi Montag left Rumor boutique with two options to wear to her birthday, a short sexy Voom by Joy Han silver dress and a red mini by Flavio Castellani . Looks like she decided on wearing the silver number with Jour & Nuit pumps and Andarei clutch to finish off the look.

Now the real question is, is the relationship between Heidi and Spencer for real?
