The Latest In Party Accessories, According to Audrina Patridge: Boob Balloons

If you ask us, this looks just like a 'Hills' bash.

Audrina Patridge was known for her sexy style and dressing to the nines while attending the hottest bashes during her "Hills" tenure. While not much has changed in the fashion department for the silver and purple-haired beauty, she just opted for some eye-catching accessories during a sunny gathering. Namely: boob balloons.

The "1st Look" host shared some snapshots from a recent soiree, and let's just say that the white- and pink-tinted decorations would definitely have spiced up an old-school ragefest at Les Deux with the Tinseltown crew.

"Boobie balloons," Drina simply captioned the pic above, which finds the SoCal lady inflating the party items with some gals and appropriately posing with the faux breast(s).

So what was the occasion to break out the twins #boobieloons? The 33rd birthday of her longtime on-again off-again on-again beau, "stud" Corey Bohan!

And natch, the BMX athlete and man of the hour -- who we last saw with Drina on Halloween night during a rather emotional excursion -- had a bit of fun with the balloons. It's the Aussie hunk's special day, after all.
