A friend reveals to Life & Style that the actress recently turned down a $30,000 party-appearance fee just to keep herself on track.

"Before Lindsay went to rehab, she would pretty much turn up any where if someone paid the right price, but things are different now," a friend tells Life & Style. "She's been offered tens of thousands of dollars to attend events and make other appearances, but has turned them all down in order to maintain her sobriety ... She runs everything past her therapists and sober coach. She's committed to staying sober this time around."
