Dave Navarro helped Brooke Mueller get over the pain of her impending divorce from Charlie Sheen last night in Aspen -- with a crazy public make-out session!


Our Aspen spies spotted the two downstairs at Nobu, at around 8:15 PM.

We're told Jane's Addiction band members and Brooke were at the table.  Dave went outside to smoke and Brooke followed  ... once outside they began to "full on make out," as Dave had his hand on her chest.

They came back inside, got their stuff and left together.

Happy New Year!
