I’ve determined that Spencer Pratt and Heidi Montag are the human equivalent to cockroaches. They are pesky, they won’t die, they are everywhere you never want them to be and they are big, disgusting and obnoxious.

Well, even more confusing about them is the fact that we were led to believe that Heidi had filed for divorce from Spencer and that they were on the outs. So why the hell are they kissing?

Yesterday, Heidi celebrated her 24th birthday with Pratt and some friends at the Santa Barbara Zoo, later having dinner on the Santa Barbara Pier. I’m sure Spencer regaled them all on his arrest in Costa Rica and his advice on places you can carry concealed firearms while vacationing.
