Lohan will host a party on New Year's Eve in Las Vegas so says UsWeekly

Sources say she doesn't want to, but she owes Pure Management hundreds of thousands of dollars for her 21st Birthday party in Las Vegas. She cancelled the party, so she could check into rehab.

The NYE shindig will go down at LAX which Pure owns.

A source said, “She already took the money from the birthday gig and can’t afford to pay them back.”
