Ireland Baldwin has a reason to celebrate! According to an insider, the 19-year-old model "just celebrated 30 days clean and sober!"

As Breaking Celebrity News reported, Baldwin recently left Soba treatment center in Malibu, but has continued outpatient care — and it’s working.

"Ireland has been following through with her outpatient program and she is super excited about getting 30 days clean," a well-connected rehab insider tells Breaking Celebrity News exclusively.

The daughter of mega-movie stars Alec Baldwin and Kim Basinger has been doing outpatient at the facility since checking out of the inpatient program on May 2.

"She is currently doing the night and weekends outpatient program, which is designed for those people with busy schedules during the day," says the source.

"Her mother Kim has been coming with her to several of her outpatient appointments," the source reveals, "and she is very proactive with her daughter’s recovery."
