Officers claim Hilton, 29, dropped a small packet of cocaine as she pulled her lip gloss from her purse.
Nightclub mogul Waits, 34, was also arrested and charged with driving under the influence.
An hour after her release on bail, new messages began appearing on Hilton’s Twitter account. The first said: “In bed watching Family Guy. Love this show! So hilarious! Stewie is my favorite love his accent.”
Hilton’s lawyer David Chesnoff said: “I encourage people not to rush to judgement until all of the facts have been dealt with in a court of law.”
