Heidi and Spencer Suck

1/8/2008 5:26 PM PST
Tons of gross-out PDA, a photo-op or two and a stripper pole -- just another night for Heidi and Spencer.

TMZ caught the villainous "Hills" twosome at Jet at the Mirage in Vegas, where they were all over each other, even though their wedding is off.

The only thing that would've made things worse: Heidi singing.
