Spencer Pratt and Heidi Montag, aka Speidi, must have the combined IQ of a peanut. I mean, how else can you explain them buddying up to none other than Perez Hilton, who makes his living mocking the likes of Speidi?

The wonderfully vain threesome showed up for the Millions of Milkshakes in Hollywood where Speidi was promoting their “Heidi and Spencer Shake” with the gossip queen in tow. Apparently Perez was a bit confused and thought it was a banana split event and came dressed accordingly, sporting various hues of yellow. And if that wasn’t tacky enough he came equipped with several copies of his book.

I don’t know how these three don’t choke on their egos. One can wish.
