urx unit loader Spencer Pratt and Heidi Montag are (big surprise!) freeloaders

Spencerpratt___heidimontagSpencer Pratt and Heidi Montag were among the handful of celebrities attending last night’s Race to Erase MS fundraiser on trendy Melrose Place.

"The Hills" reality TV stars were handed — and posed for photos with — the special orange shopping card that gives a 20% discount to stores like Carolina Herrera, Diane von Furstenberg, Diesel,  Santa Maria Novella, salons like Frederic Fekkai, and restaurants Republic, Jumo, comme Ca, and Dolce.

The card – had Spencer and Heidi paid for it like regular folks – cost $75, which was a donation to fight MS via the Nancy Davis Foundation for Multiple Sclerosis. All the attending celebs – including big names Jon Lovitz and Tom Arnold – were carrying the card, which is valid until July 25.

When asked by L.A. Daily News columnist Joel Stratte-McClure (who just  happens to be my husband, which is why I got this scoop from his report) if they’d paid for the card, thereby making a $75 donation to fight MS, Pratt admitted that they hadn’t.

"But we are going to do some shopping with it," he countered, adding, " I have no budget when it comes to charity."

When he was told that none of the money he planned to spend at the stores, restaurants or salons would go to the charity, he looked visibly relieved.

"I didn’t know that! Dude, you just saved me a lot of money!" Pratt said with a big grin.

Did I happen to mention that Pratt and Montag don’t set foot on a red carpet or attend parties or events without being paid. According to InTouch, the blond twins have earned about $3 mill in the last two years from their TV salaries, business deals and appearance fees at clubs, parties and charity events.

But at least they earned their money last night. After all, we are running this photo of them with the orange card. And I might not have run a photo of Tom Arnold or Jon Lovitz.

In fact, I’m quite sure I wouldn’t have.
