DMX -- The First Arrest of 2010

DMX was arrested earlier today in Arizona -- and now his lawyer is reaching out to the one man who he believes can save him ... Dr. Drew Pinsky.

The details of the arrest are unclear -- but the rapper's lawyer Gary Jenkins tells us "He's been battling addiction for some time and he's in need of treatment."

Jenkins also tells us, "We're hoping that maybe Dr. Drew might be able to help him."

DMX -- aka Earl Simmons -- was arrested a bazillion times over the last two years for all sorts of reasons ... including drug charges.

Jenkins added, "He's a talented man ... we're praying for him."

UPDATE 5:04 PM PT: We've also learned more details of DMX's arrest. We're told he allegedly violated the terms of his probation by using illegal drugs.

UPDATE 8:06 PM PT: DMX has been booked on five counts of probation violation and is being held without bond. We're also told he launched a few expletives during his initial court hearing tonight -- we'll have video of it in the morning ... so stay tuned!
