Ludacris just pulled in ridiculous bank to perform at an exclusive Xmas party for some millionaire -- in fact, TMZ has learned, the contract was worth nearly $100K ... and he wasn't even the only star there.


A rep for millionaire entrepreneur Jason Hope tells TMZ ... Luda was paid to perform a 45-minute set for party-goers at Hope's pad in Arizona -- and get this ... Snooki, Stephanie Pratt, Lo Bosworth, and a bunch of other celebs got money to show up too.

Altogether, were told Hope dropped nearly $200,000 to get the famous faces to attend --

-- Snooki got $17,500
-- Lo and Stephanie got $12,500 each
-- "Breaking Bad" star Aaron Paul got $16,000
-- Kardashian stepfather Bruce Jenner got $15,000
-- Giuliana and Bill Rancic got $15,000 total
-- Dean Cain got $5,000.

According to Hope's rep, the whole party ran the guy nearly $500,000 total. Who said money can't buy friends?

"The Hills" extras Stephanie Pratt and Lo Bosworth were actually invited to the same event in West Hollywood and no drama ensued.



Question is ...

An attorney for Stephanie Pratt just pled not guilty on her behalf to a charge of misdemeanor DUI -- and her lawyer says the "Hills" star will check in to rehab.

Pratt's lawyer said she will enroll in a 30-day residential facility.

As we first reported, Pratt was pulled over at 3:45 AM on October 18 after leaving Holly Montag's birthday party.

Pratt's two breathalyzer tests registered .08 and .09 -- the legal limit is .08 -- so she was arrested and held on $5,000 bail.

If convicted, Pratt could face up to six months in jail and a $1,000 fine.

A .08 is a .08 no matter how you look at it -- so Stephanie Pratt was formally charged with suspicion of DUI today after her arrest two Sundays ago in Hollywood.

Drunk driving is drunk driving -- but as far as DUIs go, Stephanie Pratt is no Gary Collins.

We've learned the "Hills" star took two breathalyzer tests after she was pulled over in Hollywood early Sunday morning. The first was .08, the second was a .09.

The legal limit in California is .08.

She was not stopped because she was driving erratically, but because of an equipment violation.

As we first reported, Pratt felt the cops were lying in wait for her as she left a club in Hollywood.

Pratt was held on $5,000 bail and released Sunday afternoon.

Stephanie Pratt spent Saturday evening at a birthday party in Hollywood for Holly Montag. She spent Sunday morning in jail after she was arrested for DUI.



A good time was had by all. Maybe too good.

UPDATE -- A source close to Pratt tells us Stephanie had just left Holly Montag's birthday party when she was pulled over. Our source says cops watched Stephanie get in her car and were waiting to bust her.

TMZ has learned Stephanie Pratt was arrested for suspicion of driving under the influence early this morning in Hollywood.

Law enforcement tells us Pratt, who appears frequently on MTV's "The Hills," was busted this morning at 3:45 AM PT in Hollywood.

She was taken into custody. Her bail is set at $5,000.

Pratt is still in custody. She's just been booked.

UPDATE: So how's this for crazy. We're told some spectators who had just gotten out of a club saw Pratt get busted. Some started taking pictures, which ticked off some of the others and a big fight broke out on the street while Stephanie was being cuffed. But Steph was the only one taken into custody.
