On Monday, Lohan was seen jogging on the beach during a break from her stay at Promises rehab center in Malibu.

Saturday, with a brand new iPhone in her hand, Lindsay Lohan stopped by the boutique Planet Blue.

She was seen the day before, on Friday, with friends – a male and a female listening to the piano at the Chateau Marmont. The star drank tea, diet coke, and water, according to an observer at the hotspot, who added: "She's turned things around, at least for now."

And last Wednesday night she attended an AA meeting in Santa Monica before meeting pals for dinner at Katsuya in Brentwood – with a stop at Promises in between.

"She came in with a whole bunch of friends, there were like seven of them, and she walked in incognito, super low-key," a fellow diner tells PEOPLE. "They sat down for some sushi and were just really enjoying themselves. She wasn't really noticed at all and was just happy, in a good mood."
