Heidi Montag skipped her sister’s birthday party because they wouldn’t pay her. You read that correctly. Heidi wanted an appearance fee to show up at her sister Holly’s birthday party Saturday and the club promoters wouldn’t give it to her. Heidi refused to attend.

That’s how you know Hollywood has gotten to your head. You skip your sibling’s birthday because you aren’t paid to go. How low can one person sink? From Fox News:

 ”Holly was really wishing that her sister could just be a sister and stop by her birthday party, but Heidi only goes places if she is getting paid,” an insider snitched to Tarts. “I mean, this is her sister and she wouldn’t even show up without a fee. That’s disgusting.”

The evening ended up garnering publicity, however, as the birthday girl’s BFF and MTV co-star, Stephanie Pratt, was arrested on suspicion of a DUI after leaving. This isn’t the first time the 23-year-old has funded herself on the wrong side of the law. In May 2006 Miss Pratt was arrested in Hawaii for second-degree theft and drug violations.

Gee. No wonder why the sisters Pratt and Montag have drinking problems. Look what their family is like! Heidi, you need to get a clue and get rid of your money ideals.
