It had been rumored earlier this week that Lindsay Lohan would be leaving rehab this weekend.  Her mother says those rumors are “Not true.”

“Not true,” the actress’s mother, Dina Lohan, 45, told Access Hollywood in an e-mail, “staying in Utah.”

Lindsay’s treatment at the facility began last month, following her early morning July 24 arrest in Santa Monica, Calif., on suspicion of drunken driving after a brief car chase.

LiLo sounds, or at least the length of her rehab stay, make it seem as if she is serious about getting cleaned up.
