UNDATED (CNN) - If you collect Lindsay Lohan mug shots, here's a new addition to your gallery.

The actress is heading back to rehab after a judge sentenced her to 90-days at a locked-in facility.

It's part of a plea deal for a probation violation.

Under the deal, the actress entered pleas of no contest on two misdemeanor charges relating to a traffic accident last summer.

And she did not challenge the finding that she violated her shoplifting probation with those convictions.

Lohan has spent 250 days in five rehab facilities since January 2007, including one long court-ordered stint after a failed drug test.
